Abstract Aims This study looks whether the response of soil management (liming and nitrogen fertilization) on incidence Fusarium wilt (Foc Race 1) in Gros Michel banana ( Musa AAA) varies with different properties. Methods The effect inoculation Foc 1 was studied a factorial greenhouse trial samples from eight representative types Costa Rican region, two pH levels; three levels N-fertilization....

ABSTRACT Modeling the response of soils to liming is important for understanding neutralization reactions and predicting lime residual effects. Models based on simple or quadratic polynomial equations are most used due their simplicity ease fitting; however, they fail reproduce a realistic soil liming, indicating decrease in pH as dose increased after reaching maximum point. Thus, several nonli...

(The effect of different soil properties on arbuscular mycorrhizal colonization of peanuts, sorghum and maize). Arbuscular mycorrhizal fungi (AMF) are important for plant growth since they increase mineral influx. However, symbiosis efficiency is affected by many environmental factors. This study evaluated the effects of different treatments (+/phosphorus; +/liming; +/organic matter; field, san...

Assessing mitigation of phosphorus (P) leaching from subsurface drainage systems is challenging due to high spatial and temporal variation in leaching. Mean measured total P leaching from a clayey soil in an eight-year study period (four replicates per treatment) was (kg ha-1 year-1): 1.21 from shallow autumn tillage (ShT), 0.84 from unfertilised fallow (UF), 0.81 from conventional autumn ploug...

Transport of phosphorus (P) from agricultural fields to water bodies deteriorates water quality and causes eutrophication. To reduce P losses and optimize P use efficiency by crops, better knowledge is needed of P turnover in soil and the efficiency of best management practices (BMPs). In this review, we examined these issues using results from 10 Swedish long-term soil fertility trials and var...

Microbial reduction of arsenate [As(V)] to arsenite [As(III)] and the subsequent effects on As mobilization in contaminated mine tailings were studied under transport conditions. Molecular analysis of bacterial populations and traditional isolation techniques were used in conjunction with column experiments designed to observe relationships among pH (limed vs unlimed treatments), redox potentia...

The diversity of bacterial isolates from soil in response to different plants (control, Brachiaria ruziziensis and Cajanus cajan), fertilization (control, simple superphosphate and rock phosphate) and liming (with and without lime) was evaluated. Phenotypic and physiological characteristics of the isolates were recorded and organized in a file to identify the bacteria. Among the isolates, 95% w...

Three techniques for treating fish ponds with agricultural limestone were evaluated in ponds with clayey soils in Brazil and in ponds with sandy soils in South Africa. Amounts of agricultural limestone equal to the lime requirement of bottom soils were applied by the following methods to each of three ponds: (1) direct application over the pond surface; (2) spread uniformly over the bottom of t...

Gypsum is being applied to ameliorate subsoil acidity and to overcome the problem of very slow lime movement from surface lime applications. Reduced Crude Conversion Spent Lime (RCCSL) containing anhydrite was evaluated for use as a liming material with specific consideration given to the movement of sulfate into the acid subsoil. Agricultural lime and RCCSL were applied at 0, 0.5, 1.0, and 1.5...
