ABSTRACT Tree integration into pasture systems modifies microclimatic and edaphic conditions that can influence forage dynamics, especially during the establishment of overseeding annual cool‐season forage species in subtropical regions. This study evaluated the agronomic performance of black oat (Avena strigosa), overseeded into a warm‐season ...

Inceptisol Physicochemical Attributes in the Caatinga Biome Agroforestry Systems [PDF]
ABSTRACT We evaluated two areas of sustainable management within the Caatinga and one area of conventional agricultural cultivation to compare their physicochemical attributes with those of native forest. The management strategies were as follows: (1) thinning of savanna; (2) thinning of strips; (3) conventional tillage with plowing and harrowing; and (

Influence of cutting frequency and height on phytoestrogen levels in red clover and white clover
Abstract Phytoestrogens are a class of secondary compounds naturally produced by some forage legumes, including red clover (Trifolium pratense L.) and white clover (Trifolium repens L.). Previous research showed that phytoestrogens can have beneficial and negative effects on animal health and reproductive function.

Water Cationic Composition on Potassium Displacement in Tropical Soils
ABSTRACT This study aimed to evaluate the interplay between water hardness, sodium adsorption ratio (SAR), and electrical conductivity (EC); with tropical soil physical, chemical, and mineralogical characteristics on the displacement K+. The water quality treatments represented solutions suitable and not suitable for irrigation, with varying levels of ...

A hysteretic model predicts a time lag in the response of herbaceous layer variables (e.g., cover, diversity) to decreasing N deposition. To the contrary, virtually all such variables displayed a surprising sensitivity to decreased N. ABSTRACT Increases in nitrogen (N) emissions during the 20th century resulted in the atmospheric deposition of N ...

Growth and yield of teak stands at different spacing [PDF]
: The objective of this work was to evaluate the growth and yield of teak (Tectona grandis) stands at different spacing and in different soil classes. Twelve spacing were evaluated in an Inceptisol and Oxisol, in plots with an area of 1,505 or 1,548 m2 ...
