Each soil type has its own challenge! In this article, we focus on four soil compositions and their main challenges: clay, loam, sand, and humiferous.
Each agricultural soil has physical and chemical properties that influence crop growth. Texture, water retention capacity, structure, and depth: all factors that determine the timing of interventions, the choice of crops, and even irrigation needs. Understanding the specific characteristics of your soil type allows you to better understand climatic hazards, for greater precision in adapting your cultivation practices.
Soils composed primarily of clay are rich and capable of retaining water, but their compact structure makes early sowing difficult. They become waterlogged in winter and dry out, forming cracks in summer.
One of the major challenges is to aim for a period when the soil is neither too wet nor too dry, to intervene without compacting, whatever strategy is chosen : direct seeding, reduced work or conventional preparation.
On the Sencrop app, weather readings for your fields are transmitted live. This way, you can track rainfall in real time to choose the right moment to sow. You can also set up alerts to be notified (text message, call) when the conditions are right (e.g., 5 days without rain).
Finally, follow the forecasts for your field for up to 7 days, and anticipate the ideal window.
Highly fertile and easy to work, silt-rich soils suffer from low structural stability. Heavy rainfall can create a surface crust, preventing seedling emergence. The soil then becomes compacted and impermeable, hindering infiltration and growth.
The Sencrop app allows farmers to anticipate heavy rain and intervene before (cover the soil, limit fine work) or after (use a light tool to break the crust).
To use on the Sencrop application:
When it is predominantly sandy, the soil is light, well-drained, and easy to work. However, it has low water retention capacity. Water quickly seeps deep into the soil, sometimes carrying nutrients with it. This exposes crops to a high risk of water stress, particularly during the summer or in the absence of rain. To optimise yields, irrigation must be frequent, targeted, and adjusted to the plants' actual needs.
Among the two weather stations offered by Sencrop for managing irrigation, the Irricrop Pack (Raincrop + Windcrop +Solarcrop) allows you to accurately calculate evapotranspiration (ETP), the main cause of water loss in sandy soil. In addition to the transmitted weather data, you configure your soil type and your crop to adapt the monitoring graph and model the available water reserve. This will make it easy to detect when your soil is experiencing water stress.
Each farmer can thus irrigate wisely to optimise their yields, while avoiding both water stress and water waste.
Humiferous soils, often derived from peat environments, are highly fertile thanks to their high organic matter content. Their spongy structure allows them to effectively retain water, which is an advantage during dry periods. However, this retention capacity becomes a disadvantage in the event of excessive rainfall: the soil can remain waterlogged, slowing crop emergence and significantly increasing the risk of disease, particularly fungal disease. Conversely, during prolonged dry periods, the soil can become hydrophobic and difficult to re-wet.
On Humiferous soil, excessive humidity constitutes a major risk: it encourages the development of fungal diseases (mildew, powdery mildew, rust, etc.) and complicates field work.
To secure your agronomic decisions despite these constraints, Sencrop recommends the use of:
Understanding the limitations of each agricultural soil allows you to make the right decisions at the right time. Precision agriculture today relies on reliable microclimatic data, taken directly from the field. Regardless of the soil you're working on, tools exist to manage your crops with greater peace of mind.

Potato late blight is the most feared fungal disease among potato growers. Without proper monitoring and treatment, yield losses can reach 80 to 100% of the harvest. Understanding the disease, knowing how to recognise it and anticipating its onset are now essential to securing your crops. What Is Potato Late
Nitrogen, fertilizers, pesticides: your inputs are expensive. Very expensive. And when heavy rain hits right after application, some of it can literally disappear beneath your feet. Leaching is an often underestimated phenomenon, but one that can have a direct impact on yield, treatment effectiveness… and your wallet. 💡 Good news: there
