L'étude a été réalisée au Centre de recherche agroforestière, G.B. Pant University of Agriculture and Technology, Pantnagar, en 2010-11 pour étudier l'effet des densités d'arbres sur les propriétés physico-biochimiques du sol sous un système agrisilviculturel à base de peuplier de huit ans. Le traitement se composait de quatre densités d'arbres comme parcelle principale et de quatre profondeurs de sol car la sous-parcelle a été étudiée dans une conception de parcelle divisée avec trois réplications. La densité du peuplier a montré un effet significatif sur les propriétés physico-chimiques et biologiques du profil du sol. La densité apparente du sol était significativement plus faible sous les arbres par rapport à la culture unique. Les propriétés chimiques du sol, à savoir le carbone, le carbone organique, l'azote disponible, le phosphore disponible, le calcium échangeable, le zinc extractible DTPA, le cuivre et le manganèse étaient significativement plus élevées sous les arbres que la culture unique. L'amélioration des propriétés physico-chimiques et biologiques du sol sous les arbres peut être attribuée à une plus grande quantité d'ajout de biomasse par la chute de litière et le recyclage des racines fines sous les arbres par rapport à la culture unique. Ainsi, on peut conclure que les propriétés du sol ont été considérablement améliorées dans le système agroforestier à base de peuplier que la culture unique.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The study was carried out at Agroforestry Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, during 2010-11 to study the effect of tree densities on soil physico-bio-chemical properties under eight year old poplar based agrisilvicultural system. Treatment consisted of four tree densities as main plot and four soil depths as sub-plot were studied in split plot design with three replications.Poplar tree density showed significant effect on soil physico- chemical and biological properties of soil profile. The soil bulk density was significantly lower under trees compared to sole crop.The soil chemical properties viz., carbon, organic carbon, available nitrogen, available phosphorus, exchangeable calcium, DTPA extractable zinc, copper and manganese were significantly higher under trees than sole crop. The improvement in the soil physico- chemical and biological properties under the trees can be attributed to higher amount of biomass addition through litter fall and fine root recycling under trees compared to sole crop. Thus it can be concluded that soil properties were significantly improved under poplar based agroforestry system than sole crop. 124 pp. Englisch. N° de réf. du vendeur 9783659692963
