Accumulation of phosphorus fractions in contrasting soils under long-term phosphate fertilization. [PDF]

J Environ Qual
Abstract Understanding phosphorus (P) dynamics in soils under conservation agriculture remains challenging because the long‐term effects of fertilization rates and soil texture on P accumulation, availability, and environmental risk are not being fully understood. This study evaluated P fraction accumulation and saturation indices across soil layers in

Simulating solute transport in an aggregated soil with the dual-porosity model: measured and optimized parameter values [PDF]

, 1994
The capability of the first-order, dual-porosity model, which explicitly accounts for non-ideal transport caused by the presence of ‘immobile’ water, to predict the non-ideal transport of non-sorbing solute in a constructed aggregated soil has been ...

Quantifying the influence of eucalyptus bark and corncob biochars on the physico-chemical properties of a tropical oxisol under two soil tillage modes

International Journal of Recycling of Organic Waste in Agriculture, 2019
This study aimed to assess the impact of two biochars applied at the rate of 15 t ha−1 on physico-chemical parameters of an oxisol in Cameroon. The biochars were made from slow pyrolysis (~ 300 °C, 4 h) of eucalyptus tree bark and corncobs and then ...

Aplicação superficial de gesso num Latossolo de baixa acidez sob sistema plantio direto [PDF]

, 2011
The conditions in which a favorable response to a gypsum application can be expected on crop yields are not clear. A 3-year field trial was carried out to evaluate the effects of gypsum application on soil chemical attributes and nutrition and yield of ...

Influence of notillage on carbon sequestration and erosion in Brazil [PDF]

, 2004
Les sols constituent le plus gros réservoir superficiel de C (hors les roches carbonatées), environ 1500 Gt C, ce qui équivaut à presque trois fois la quantité stockée dans la biomasse terrestre, et deux fois celle de l'atmosphère.

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

Land Degradation &Development, EarlyView.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...
