The effects of root-induced changes in soil structure on water and nutrient acquisition and their eventual feedback on plant growth and crop production are important aspects of future food security. The Root System Ideotypes for Soil Resource Capture The principal roles of the root system are to...
Soil salinization and/or alkalization is a major constraint to crop production worldwide. Approximately 60% of the cultivated land is affected by salt, over half of which is alkalized. Alkaline soils are characterized by high alkalinity and typically high salinity, which creates a complex saline-al...
Biochar soil amendment improves crop productivity mainly by increasing nutrient use efficiency and water holding capacity. However, improvements to crop production are often recorded in highly degraded and nutrient-poor soils, while its application to fertile and healthy soils does not always increase cro...
Soils are an important source of nitrogen in many of the world’s cropping systems. Especially in low-input production systems, nitrogen release from soil organic matter turn-over is the major part of the crop’s nitrogen supply and research suggests tha
Adding charcoal to soil can significantly increase seed germination, plant growth, and crop yields (Table 1).Chidumayo(1994) reported generally better seed germi-nation (30%enhancement), shoot heights (24%) and biomass production (13%) among seven indigenous woody plants on soils under charcoal...
control of plant pathogens either by stimulation of the plant’s defense mechanisms or by microbial antagonism [11,13]. Some BEs induce plant growth by stimulating the plant’s own hormone production such as auxins or cytokinins [13,14], or by producing directly hormone-like compounds [15]. ...
They are able to easily multiply in a rhizosphere to promote plant growth and yield (Vessey 2003). Farmers where not applied chemical fertilizers in manage and balance way for crop production, because they are not aware about how much fertilizer is necessary for plant and it varies from crop ...
