Agricultural weeding: benefits, techniques and tools

Grassland is the maintenance of a herbaceous cover between crop rows, contributing to soil protection, biodiversity and environmental sustainability. In this article, we will explore the main benefits of grass cover, the most effective techniques and recommended agricultural machinery to optimise crop management.

The benefits of grassing for vineyards, olive groves and orchards

1. Soil conservation and improved fertility

One of the main advantages of grassing is its ability to prevent erosion and improve soil structure. Thanks to the presence of herbaceous roots, the soil remains more stable, favouring moisture retention and the accumulation of organic matter, which reduces the need for chemical fertilisers.



2. Increased biodiversity and ecological balance

Grassland is ideal for those seeking sustainable agriculture. Herbaceous species attract beneficial insects such as bees and other pollinators, as well as natural predators of pests, reducing the use of pesticides and creating a healthier, more balanced environment for crops.



3. Improved plant health and fruit quality

Fertility and soil balance directly influence crop quality. In vineyards with grassland, for example, higher quality grapes are produced that are more resistant to water and climatic stress. In orchards and olive groves, grassing helps to maintain constant moisture and protect the roots.

Grassland techniques: natural and sown

There are two main methods of grassing:


Natural grassing

Natural grassing lets the grass grow spontaneously. It is an economical solution, but may require more careful management, especially for those who prefer a natural approach without specific grass species control.


Sown turf

Sown turf allows the selection of specific plants such as clover, vetch and grasses (e.g. barley and fescue), which enrich the soil and limit competition with crops. With this technique, targeted benefits can be obtained by choosing species that favour water retention, reduce weeds or improve soil quality.

How to optimize grassland according to season and climate

Grassing may require seasonal management, especially in arid climates where competition for water could be a problem. In such cases, it is advisable to adopt controlled or temporary grassland techniques, where grass is allowed to grow only at certain times of the year to avoid competition with crops.

Agricultural machinery for optimal grassland management

Although grass cover has many advantages, too much grass cover can compete with crops for water and nutrients and attract pests. To avoid these risks, careful grassland management is essential. Here are the best farm machinery for efficient management:

Mulchers e weeders

These machines are essential for controlling grass growth and keeping the soil aerated and free of weeds. Mulchers cut and shred grass, keeping it at an optimal height without damaging surrounding crops. Weeders, on the other hand, help break up the surface crust of the soil, promoting better aeration and stimulating balanced growth of the grass cover.

Mechanical weeders

Mechanical weed killers allow for weed control without the use of chemical herbicides, a particularly popular choice in organic farming. These tools ensure that crops remain protected while weeds are effectively removed.

Mowers

Mowers are ideal for keeping grass height under control, especially in inter-row cultivation in vineyards and orchards. Unlike mulchers, mowers cut grass without shredding it, which can be advantageous when you want to maintain an intact turf.

Mowing periods can be variable depending on the season and type of crop. For example, in spring and summer, when vegetation is most active, more frequent mowing may be required to avoid excessive water competition. In periods when plants are resting (such as in winter), on the other hand, the number of interventions can be reduced.

Mowing grass at proper maturity promotes organic mineralization, releasing nutrients into the soil, such as phosphorus and potassium, and supporting humus formation.

Power harrows or flexible tooth harrows

Harrows are very useful in preparing the soil for grassing, facilitating seed germination and improving soil structure. They are especially good for breaking up the surface crust of the soil without disturbing the root system of crops.
Harrows can be used before cover crop planting or to lightly remove weeds, promoting soft, aerated soil.

Our agricultural machinery is designed to adapt to different crop requirements and ensure optimal cover crop management even on steeply sloping soils.

Our customers successfully use our machinery in vineyards and orchards to maintain grass cover without damaging crops.
