Mathematical models help select crops to combat drought

According to the Hydrological Processes, an international mathematical group has modeled to help determine how plants affect the conservation of water resources in different climatic conditions and in different soil types.

Models from scientists from the United Kingdom, the United States and Germany can help predict the complex relationship between soil type , soil vegetation and water regimes - meaning that all moisture comes from the atmosphere and soil. as well as moisture returning to the atmosphere.

The model, called EcH2o-iso, helps determine how long water lasts in different soil types and natural landscapes. For example, if the forest grows under beach conditions, the water will evaporate into the atmosphere and fall into the acceleration cycle and vice versa, the grass will retain moisture in the ground.

A mathematical model will help farmers conserve water resources and combat climate change. In addition, different types of vegetation help save soil from erosion due to rain and weathering. The scientists also succeeded in examining computer calculations in field studies, conducted near Lake Grozer-Stechlins in northern Germany.

In agriculture, this model is useful for predicting the effect of vegetation on the humidity required in this area and how it will change after planting certain crops.

According to the authors of the work, earlier models viewed the landscape with vegetation as something static and did not reflect the physiological processes of plants, such as water evaporation - water evaporation. from the surface of leaves and soil, as well as the interaction between biomass production and soil condition.
