How does nutrient leaching affect crop health

:: Monday, March 3, 2025 :: Posted By Fabiano Silvestrin
Soil can lose essential water-soluble nutrients needed for crop growth due to excessive rain or irrigation. This process is referred to as leaching. Depending on factors like soil structure and local climate, some soils may leach more than others.

Boron mobility vs immobility in plant species

:: Wednesday, June 19, 2024 :: Posted By Fabiano Silvestrin
Boron mobility vs immobility in plant species
Boron (B) deficiency is directly affected by boron mobility or immobility in plants. In those species in which boron is immobile in the phloem, foliar-applied boron will not be translocated from the site of application. This means there is not enough boron to adequately supply the plant cells that are required for tissue formation. In those species where boron is immobile via phloem, boron must be applied via soil.
