When soil is left bare, rain hits the surface directly, triggering runoff and washing away the most fertile layer of the land. The problem does not end when the rain stops: the soil loses its structure, its nutrients and its productive capacity.

A phenomenon that is growing in frequency — and in cost

The data is clear: extreme rainfall events have increased in both frequency and intensity over recent decades. For farmers, this means more erosion, more damage and greater uncertainty in each season.

The economic impact is not only measured in crop losses. Soil recovery is slow and costly. Each centimetre of topsoil that is washed away represents years of natural formation and, in many cases, an investment that cannot be recovered quickly.

The soil: the most valuable and most vulnerable resource

Agriculture depends on living, well-structured soil that can infiltrate and store water. Yet intense rainfall causes:

• Loss of organic matter
• Soil compaction
• Removal of essential nutrients
• Formation of gullies and water erosion
• Reduced infiltration capacity
• Stress to crops in the periods that follow

In permanent crops such as olives, almonds, vineyards and pistachios, the soil between trees or vines is particularly exposed. Without protection, each heavy rain event is an opportunity lost — not just for the current season, but for the long-term productive capacity of the farm.

The importance of cover crops against intense rainfall

Cover crops are one of the most effective tools available for preventing erosion and protecting soil structure in the face of intense rain.

A well-established cover crop acts as a buffer between the rain and the soil: it absorbs the impact of drops, slows surface runoff, improves infiltration and keeps the soil in place.

Beyond protection, cover crops also contribute to building organic matter, improving soil biology and making the land more resilient to climatic stress over time.

Green Series: natural soil protection

The Green Series range by Agrosemillas has been specifically developed to provide effective protection against erosion in permanent and arable crops, adapting to different soil types, climates and management needs.

Its mixtures are formulated to establish quickly, develop a strong root network and provide consistent surface coverage — exactly what is needed when heavy rain is on its way.

Each mix within the Green Series range is designed for a specific purpose, whether it is to protect against erosion, improve soil biology, reduce compaction or contribute to environmental compliance.

The future of farming depends on caring for the soil

Climate change is not coming — it is already here, and its effects on agriculture are real and measurable. Adapting to a context of more frequent and more intense rainfall requires going beyond reactive measures and adopting a long-term soil management strategy.

Cover crops are not just a protection tool. They are an investment in the resilience and productive future of the farm.

Protect your soil before the next rain. With Green Series, you are always one step ahead.

After a wildfire, the land is left bare, fragile and exposed. The loss of vegetation leaves the surface vulnerable to erosion, runoff and the loss of fertile topsoil. If heavy rain follows, the damage can worsen, washing away ash, organic matter and fine particles that are essential for the natural recovery of the ecosystem. Acting quickly and with sound technical knowledge is therefore critical.

Every year, wildfires devastate thousands of hectares of woodland

The destruction caused by fire goes far beyond what the eye can see. While the loss of trees, shrubs and vegetation is visible from the first day, the damage to the soil — its structure, its biology, its capacity for recovery — often goes unnoticed.

Yet it is precisely this invisible damage that will determine whether the land can regenerate in the months and years ahead.

The risk does not end when the fire is put out

A wildfire does not only destroy vegetation. It also alters the soil structure, reduces its water retention capacity and can hinder the emergence of new plant life. In sloped terrain, the risk is even greater.

When heavy rain falls on bare, burned soil, it cannot infiltrate properly. Water runs off the surface at speed, carrying with it the most valuable layer of the land — the topsoil.

This is not just an environmental problem. It is an agricultural, economic and ecological problem. Every centimetre of topsoil lost represents years of slow formation, difficult to recover and even harder to replace.

Cover crops: a tool to fix, protect and recover

The application of cover crops in burned areas is one of the most effective technical responses available in the first weeks after a fire.

Cover crops serve several simultaneous functions: they protect the surface from the direct impact of rain, reduce runoff, fix the soil with their root system and create the conditions for natural recovery of organic matter.

They are not a decorative or symbolic measure. They are a technical intervention backed by proven results in erosion control and post-fire recovery.

Green Series: a solution developed for the most adverse conditions

Not all cover crop mixtures are suitable for post-fire intervention. The Green Series range by Agrosemillas has been developed with species selected for their rapid establishment capacity, resistance to harsh conditions and ability to perform across diverse soil types and climates.

The species used in Green Series post-fire mixtures are particularly relevant for their germination speed, resilience, adaptability and functionality.

Drone application: speed and efficiency across large areas

After a wildfire, many areas present serious access challenges. There are slopes, unstable terrain, burned debris and extensive zones where manual or machinery-based intervention can be complex.

Applying cover crops by drone makes it possible to act swiftly across large surfaces, cutting response times and enabling seeding in areas where ground access is limited.

This technology combines precision, efficiency and rapid response. And in a burned soil, time matters. The sooner the surface is protected, the lower the risk of soil loss when the first rains arrive.

A responsible response for burned woodland

Recovering land affected by fire requires planning, technical knowledge and solutions adapted to each terrain. Not all soils are the same, and not all interventions are equally effective.

At Agrosemillas, we work with technicians, land managers and public bodies to provide solutions based on real knowledge of each situation.

Protecting the soil after a fire is the first step towards recovery. The rest follows from there.

A decision that determines farm profitability

In woody crops such as olive groves, almond orchards, vineyards, or pistachio, soil management directly affects profitability, crop health, and farm sustainability.

Not all strategies deliver the same results. Choosing between spontaneous ground cover, bare soil, or specific cover crops completely changes the farm’s balance.

The three most common soil management models

Soil is not only the physical base of the crop. It is an active element that determines water availability, soil structure, biodiversity, and the level of intervention required each season.

In this context, there are three particularly common soil management approaches in woody crops.

1. Spontaneous ground cover or weeds

This is a common situation when there is no targeted establishment. The soil is covered by spontaneous vegetation, but that cover does not always benefit the crop.

The main issue with this system is competition for resources. Weeds compete for water, nutrients, light, and space, which can reduce the performance of the main crop and increase control needs.

Although the soil is covered, it is not a planned cover nor one aimed at the farm’s agronomic efficiency.

2. Bare soil

For years, this has been a common practice on many farms. At first glance it conveys cleanliness and control, but keeping soil bare has a significant technical and economic cost.

This system requires more field operations, greater use of machinery, and more intervention to prevent unwanted vegetation. In addition, unprotected soil is more exposed to erosion, loss of structure, and poorer water retention.

In short, bare soil can involve intensive management and a high dependence on labour and maintenance.

3. Green Series cover crops

Compared with those two models, Agrosemillas proposes a third option: cover crops specifically designed to coexist with woody crops without creating significant competition.

Green Series fulfils the role of a cover crop, but with a key difference: it protects the soil, provides agronomic value, and at the same time simplifies farm management.

One of its strongest arguments is economic: its use can deliver maintenance savings of around 40%.

Why does Green Series reduce maintenance costs so much?

Because it is designed to minimise interventions and reduce soil-related work:

• It does not need mowing, which reduces machinery hours and time required
• It self-reseeds year after year for many years, avoiding new sowings
• It does not require herbicides, with the resulting economic and environmental savings
• It minimises the labour associated with farm maintenance

This makes Green Series a solution that not only protects the soil, but also improves the farm’s operational efficiency.

Beyond savings: agronomic benefits of the system

In addition to those savings, there are other relevant benefits for woody crops:

• Soil protection against erosion
• Improved soil structure
• Greater system balance
• Enhanced biodiversity
• Less competition with the main crop
• More rational and sustainable land management

It is not just about having vegetation on the soil, but about having a cover designed to provide real advantages without penalising the crop.

The future of farming is not only about producing more. It is about producing better, reducing costs, and making decisions that strengthen the farm in the medium and long term.

When Change Begins with a Decision in the Field

Agriculture changes when the decisions made in the field change. And few decisions are as significant as transitioning from conventional to organic management on a large-scale farm.

This is the case of Jesús Peñarrubia, a farmer from Ledaña (Cuenca), who manages a 300-hectare almond farm and shares his experience in this transition process with Agrosemillas.

His testimony reflects an increasingly prevalent reality in the sector: the need to produce with more sustainable criteria, without losing sight of the economic viability of the operation.

The Challenge: Producing Sustainably Without Compromising Profitability

Transitioning to organic is not just about changing inputs. It means rethinking the entire farm management: soil nutrition, weed control, cover crop management, and the relationship between all these factors.

On a 300-hectare farm, every decision is magnified. What works on a small plot doesn’t always scale well. And what seems viable in theory must be proven in the field, season after season.

Therefore, the transition to organic requires tools that provide real value without adding complexity or risk.

Green Series as an Ally in the Transition

Along this path, Green Series has become a useful tool for farms like Jesús’. Its ability to provide soil cover and agronomic value without generating significant competition with the crop aligns with the real needs of a farm in transition.

It’s not just about covering the soil. It’s about ensuring that cover works for the system, not against it.

In organic almond management, a cover crop that competes for water and nutrients can become more of a problem than a solution. Green Series, developed from Brachypodium—an indigenous species of the Mediterranean environment—offers contained growth that allows it to coexist with the crop without hindering its development.

What Green Series Offers on an Organic Almond Farm

The value of Green Series in this context is not in what it grows, but in what it solves. On a large-scale organic farm, the cover crop must fulfill several functions without creating dependencies or additional costs.

With Green Series, farmers can expect:

• Effective soil protection against erosion
• Progressive improvement of soil structure and life
• Natural control of broadleaf weeds, reducing the need for intervention
• Less competition for water and nutrients with the almond trees
• Simpler management, with fewer mowings and lower operating costs

All this translates into a more balanced, resilient farm that is more aligned with the criteria required for organic production.

An Increasingly Present Reality in the Sector

Jesús Peñarrubia’s case is not isolated. More and more farmers of woody crops—almonds, olives, pistachios, vineyards—are considering the transition to more sustainable production models. And in this process, the tools they choose make the difference between a viable transition and one that becomes complicated.

Sustainability is not a destination. It is a process built decision by decision.

Green Series: Cover, Protect, and Support

Green Series is not just another cover crop. It is a proposal designed to support the crop, not to compete with it. And on farms undergoing organic transition, this difference becomes a strategic advantage.

Because when farmers decide to change course, they need solutions that support them along the way, not ones that add uncertainty.

Because in organic farming, the best cover is not the one that grows the most. It’s the one that integrates best.

Cover Crops for Woody Crops: Not All Perform Equally

Cover crops for woody crops have become a key tool for advancing towards more efficient, profitable, and sustainable agriculture. However, not all perform equally or offer the same balance in the field.

In many cases, other cover crops exhibit much greater vegetative and root development than Green Series. And while this may seem like an advantage at first glance, in practice it can lead to increased competition with the main crop for resources such as water, nutrients, or space.

That’s where Green Series makes the difference.

Green Series fulfills the typical function of a cover crop: it protects the soil, improves its agronomic behavior, helps reduce erosion, and promotes biodiversity. But it does so without significantly competing with the main crop, making it an especially interesting solution for olive groves, almond trees, pistachios, or vineyards.

What Differentiates Green Series from Other Cover Crops

The main difference between Green Series and other cover crops lies in balance. While many cover crops develop a large aerial and root mass, Green Series maintains minimal and functional behavior. This allows the cover crop to work in favor of the agricultural system without creating competition with the main crop.

In other words: Green Series covers, protects, and adds value, but does not compete.

This approach responds to a very clear agronomic logic. A cover crop should not be measured only by how much it grows, but by how it coexists with the main crop and the real value it brings to the operation.

A Cover Crop for Woody Crops that Supports the Main Crop

In woody crops, the balance between soil cover and plant competition is fundamental. An overly aggressive cover crop can compromise the development of the main crop. A well-designed cover crop, on the other hand, improves the environment without penalizing production.

Green Series has been developed precisely for this: to be a cover crop for woody crops that protects the soil and supports the main crop without significantly depleting its resources. At Agrosemillas, we define it as a cover crop with little to no competition with woody crops such as almond, olive, pistachio, or vineyard.

Green Series: a Differentiated Proposal Based on Brachypodium

Another factor reinforcing its positioning is its botanical basis. GreenSeries Cover Crops is developed from Brachypodium, a native species of the Iberian Peninsula and the Mediterranean basin, with absolute adaptation to this environment.

Furthermore, the proposal is registered and patented at a European level, which reinforces its uniqueness and innovation within the cover crop market.

This translates into concrete advantages:

Adaptation to the environment

As a native species, Green Series exhibits natural adaptation to the conditions of the Iberian Peninsula and the Mediterranean environment.

Reduced competition with the main crop

Its behavior allows it to coexist with the main crop without aggressive competition for water or nutrients.

Controlled height and less maintenance

Green Series maintains an appropriate height, which reduces the need for constant mowing and lowers management costs.

Natural weed control

It also contributes to the control of broadleaf weeds, which can help reduce herbicide use.

Greater agronomic efficiency

The differentiated proposal of GreenSeries seeks more organic matter, less erosion, better water management, fewer inputs, and greater system resilience.

Benefits of a Cover Crop that Does Not Compete with the Main Crop

When a cover crop is well integrated into the operation, the benefits are more consistent and sustainable over time.

With Green Series, Agrosemillas offers a solution that aims to:

• Protect the soil from erosion
• Improve soil structure and stability
• Promote biodiversity
• Reduce maintenance needs
• Decrease reliance on inputs
• Provide profitability through more efficient agronomic logic

This makes Green Series not just another cover crop, but a strategic tool for farmers and operations seeking more conscious, profitable agriculture adapted to the realities of the field.

Why Green Series is a Strategic Tool for Sustainable Agriculture

Today, farmers are not just looking for a cover crop that works. They are looking for a cover crop that fits their operation, their crop, their costs, and their sustainability goals.

In this context, Green Series offers a clear proposal:

• A functional cover crop
• Reduced competition with the main crop
• Easier management
• Better adaptation to the Mediterranean environment
• A response aligned with agronomic efficiency and sustainability

Therefore, Green Series becomes a great ally for those who want to protect the soil without compromising crop yield.

Because it’s not always the fastest-growing cover crop that wins. Often, it’s the one that best supports the main crop.

Trust, Cultivate, Grow.

Beyond the rhetoric, it is important to measure how they affect maintenance costs and soil stability.

Among the most relevant indicators are the reduction of working hours, less use of herbicides, and a lower need for subsequent corrections.

A well-chosen cover crop improves soil structure and reduces the occurrence of recurring problems.

Green Series relies on proven solutions adapted to each context, which allows obtaining measurable and repeatable results.

Analyzing these data helps to make more informed decisions and justify investments to technicians and decision-makers.

Measuring the real impact turns sustainability into a management tool and not a simple concept.

La entrada Measure the real impact of cover crops se publicó primero en Agrosemillas.

Traditional plant control involves frequent clearing, herbicide use, and a high maintenance cost.

Vegetative covers allow the soil to be fixed, reduce erosion, and limit the growth of weeds when suitable species are selected.

Green Series has developed mixtures specifically designed for these environments, with hardy and controlled-growth species.

These covers require little intervention once implemented and offer stable results over time.

In addition to reducing operating costs, they improve the landscape integration of the project and reinforce its environmental component.

Incorporating vegetative covers in civil works is a technical decision that brings efficiency, sustainability, and long-term control.
