INFLUÊNCIA DA COMPACTAÇÃO DO SOLO NO DESENVOLVIMENTO DO SISTEMA RADICULAR DO FEIJÃO (Phaseolus vulgaris L.)

Abstract: RESUMOA presente pesquisa reverbera o efeito da compactação do solo no desenvolvimento da cultura do feijão Phaseolus vulgaris L. A pesquisa analisou a compactação do latossolo vermelho amarelo em recipientes, averiguou as características físicas do solo e posteriormente comparou o desenvolvimento do feijoeiro entre o solo sem compactação e o solo com maior redução do volume de lacunas, de maior coesão, resistência e diminuição da permeabilidade. A metodologia utilizada submeteu o latossolo vermelho amarelo di… Show more

“…With soil compaction, there are several negative effects on soil functioning, from its direct interference on nutrient uptake by plants, such as phosphorus and potassium that are absorbed by plants by diffusion, to reduced crop productivity, increased production costs, and reduction in leaf area due to the increased production of abscisic acid by plant roots [1]. Reduced root growth and changes in soil physical properties due to compaction have been observed in many crops, such as soybean [2][3][4][5][6][7], corn [8][9][10][11][12], wheat [13][14][15][16], edible black beans [17][18][19][20][21][22][23][24], rice [25,26], cassava [27][28][29][30][31], onions [32], Crambe [33], sugarcane [34,35], tobacco [36], cover crops [37,38], pastures/grasslands [39][40][41][42][43][44][45], and forest plantations…”
