Experiencing the adverse effects of synthetic input dependent agriculture the concept of
organic agriculture is gaining momentum. Almost 31 million hectares of land are currently …

Major factors that constrain tropical soil fertility and sustainable agriculture are low nutrient
capital, moisture stress, erosion, high P fixation, high acidity with aluminium toxicity, and low …

Stable soil aggregates and high microbial diversity are essential for efficient nutrient
recycling in soil. This study evaluated effects of different arable land-use systems on soil …

Relief may be considered an integrating factor that expresses the interaction of various soil
and plant attributes. This work aimed to analyze the potential use of landforms to predict the …

Application of organic wastes to cultivated lands can replace mineral fertilizers but may also
alter soil physical properties and enhance pollution potential. The objective of this study was …

High levels of soil phosphorus (P), combined with the status of fertilizers and manures
applied, form what is called the source term in the critical source‐area (CSA) concept. This …

O presente estudo objetivou avaliar o efeito da aplicação de calcário e fósforo sobre o
comportamento estrutural de um solo ácido com altos teores de argila e matéria orgânica …

Recycling of organic wastes via their incorporation in cultivated lands is known to alter soil
structural stability. Aggregate stability tests are commonly used to express quantitatively the …

Increasing the phosphorus (P) saturation of sandy soils may cause an increase in the rate of
transport of dissolved P to groundwater. We hypothesize that by increasing sorption of P, soil …

Dispersion is an important issue for clay leaching in soils. In paddy soils of the Red River
Delta (RRD), flooding with fresh water and relatively high leaching rates can accelerate …
