Mastic (Chatlanqosh or turpentine) is a valuable tree species in most parts of the country, particularly around the southern slopes of the Alborz and Zagros mountain range distributed. Wild Mastic tree is mainly due to the adaptability and hard rocky ground tree and needless to excessive irrigation, it doesn't usually crop. It is the mountain range of the plant, giving it less water. The soil a...

A mechanistic, biogeochemical succession model, FIRE-BGC, was used to investigate the role of fire on long-term landscape dynamics in northern Rocky Mountain coniferous forests of Glacier National Park, Montana, USA. FIRE-BGC is an individual-tree model-created by merging the gap-phase process-based model FIRESUM with the mechanistic ecosystem biogeochemical model FOREST-BGC-that has mixed spat...

Silvopastoral systems present important opportunities for increasing food production from animals. This is justified by the widening gap between production and consumer requirements, and the inability of domestic supplies to meet the projected demand up to year 2020 for foods of animal origin. Increasing productivity from animals thus necessitates the development of all possible avenues of food...

Ecosystem-based approaches to nutrient management are needed satisfy crop requirements while minimizing environmental impacts of fertilizer use. Applying residues as soil amendments can provide essential inputs from organic sources improving retention, health, water conservation, and performance. Tree hulls, husks, shells have been found contain high concentrations potassium across species incl...

The quantitative performance of wheat crop under 1-5 year old poplar plantations in irrigated agro-ecosystem was studied to ascertain the biological yield of tree and crop. Results revealed that growth and yield of wheat decreased significantly with the increase in poplar age. The per cent reduction in net grain yield was 17% under one year old poplar plantation, which increased to 52.15% under...

Tree root pruning is a potential tool for managing belowground competition when trees and crops are grown together in agroforestry systems. We investigated the effects of tree root pruning on shoot growth and root distribution of Alnus acuminata (H.B. & K.), Casuarina equisetifolia L., Grevillea robusta A. Cunn. ex R. Br., Maesopsis eminii Engl. and Markhamia lutea (Benth.) K. Schum. and on yie...
