Phosphorus (P) is one of the most limiting macronutrients for crop productivity and P
deficiency is a common phenomenon in agricultural soils worldwide. Despite long-term …

Soil organic matter (SOM) has a critical role in regulating soil phosphorus (P) dynamics and
producing phytoavailable P. However, soil P dynamics are often explained mainly by the …

Phosphate-solubilizing bacteria (PSB) reduce the negative effects of soil calcification on soil
phosphorus (P) nutrition. In this incubation study, we explored the ability of PSB (control and …

This new edition provides current information on the nutritional requirements of world crops.
It presents research on the acquisition, accumulation, transport, and functions of chemical …

This module is the eighth in a series of Extension materials designed to provide Extension
agents, Certified Crop Advisers (CCAs), consultants, and producers with pertinent …

A range of low-molecular-weight organic acids were identified in rhizosphere soil, leaf litter,
and poultry manure compost. Laboratory and greenhouse experiments were carried out to …

Humic acid (HA), a fairly stable product of decomposed organic matter that consequently
accumulates in ecological systems, enhances plant growth by chelating unavailable …

That the health of soils, plants, animals, and people are linked is an ancient idea that still
resonates. Growing evidence links farm management, soil health, and plant health but …

Humic acid (HA) might benefit plant growth by improving nutrient uptake and hormonal
effects. The effect of HA on growth, macro—and micronutrient contents, and postharvest life …

Humic acid (HA) is a relatively stable product of organic matter decomposition and thus
accumulates in environmental systems. Humic acid might benefit plant growth by chelating …
