The Effect of Fruit Trees Pruning Waste Biochar on some Soil Biological Properties under Rhizobox Conditions

The pyrolysis of fruit trees Pruning waste to be converted to biochar with microbial inoculation is a strategy improving the biological properties in calcareous soils. In order to investigate the biochar effect on some soil biological properties of the soil in the presence of microorganisms, a factorial experiment was carried out in a completely randomized design in the rhizobox under greenhous...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

Influence of controlled water supply on shoot and root development of young peach trees.

Three controlled water supply treatments were applied to 1-year-old peach trees grown in root observation boxes. The treatments were: I(0), growth medium maintained at 50% field capacity; I(1), water supplied when daily net tree stem diameter change was negative or zero for 1 day; I(3) as for I(1) except that water was applied after net daily stem diameter change was negative or zero for 3 cons...

Root activity patterns in an Amazonian agroforest with fruit trees

In a multi-strata agroforestry system in the central Amazon near Manaus, we studied the root activity distribution of different fruit trees and a legume cover crop in comparison to monocultures and a secondary forest site. Uptake of applied P, P and N from 0.1, 0.6 and 1.5 m depth was compared in both the dry and wet season. The results obtained with P were similar to those with N but showed a ...
