Many factors including climate, type of rootstock, soil properties, geological factors, plant nutrition and irrigation affect the quantity and quality of orange fruit. In this study, the relations between citrus orchards conditions, their soil properties and leaf elements concentration and fruit quality were evaluated. The experiment was conducted as a randomized complete block design and soil,...
Harvest operations conducted under conditions of high soil moisture on a wet pine flat in South Carolina resulted in a high degree of soil surface disturbance. Less soil surface disturbance occurred when soil moisture content was lower. Soil strength varied by soil disturbance class in wet harvested locations and highly disturbed areas were associated with low soil strength and elevated levels ...
Based on the characteristics of Lycoris aurea (L. aurea) natural distribution and local soil types, we selected four representative types of soil, including humus soil, sandy soil, garden soil and yellow-brown soil, for conducting the cultivation experiments to investigate key soil factors influencing its growth and development and to select the soil types suitable for cultivating it. We found ...
Plant litter is an important factor for soil conservation and sustainability that could modify soil chemical properties and increase the plant biomass production. The aim of this research was to compare plant litter chemical composition and its effects on soil properties in three species including Hordeum bulbosum, Poa bulbosa, Bromus tectorum. First, soil samples were taken in the depth of 0-3...
23 24 Beside biotic interactions, habitat preference and dispersal ability of species play a prominent 25 role in the building of animal species assemblages. However, these traits are usually very poorly 26 documented for soil organisms. A soil transfer experiment was designed to study habitat preference 27 (including land-use and soil preference) and dispersal ability of soil springtail specie...

مقایسه روشهای شبکه عصبی مصنوعی و رگرسیونی برای پیشبینی هدایت هیدرولیکی اشباع خاکهای استان خوزستان
Direct measurement of soil hydraulic characteristics is costly and time-consuming. Also, the method is partly unreliable due to soil heterogeneity and laboratory errors. Instead, soil hydraulic characteristics can be predicted using readily available data such as soil texture and bulk density using pedotransfer functions (PTFs). Artificial neural networks (ANNs) and statistical regression are t...
The potential of coupling soil moisture and a Universal Soil Loss Equation-based (USLE-based) model for event soil loss estimation at plot scale is carefully investigated at the Masse area, in central Italy. The derived model, named Soil Moisture for Erosion (SM4E), is applied by considering the unavailability of in situ soil moisture measurements, by using the data predicted by a soil water ba...
Re-vegetation is an important practice for eco-environmental rebuilding of degraded environments. Accordingly, re-vegetation has been widely used to reduce erosion and protect soils against degradation in the Loess Plateau. However, little research has been conducted to study the effects of long-term re-vegetation on soil properties, which is essential to reveal corresponding changes in soil qu...
this study was conducted to investigate the type and origin of clay minerals via several profiles in lordegan hilly lands. the profiles were located in two kinds of land uses including forest and dry farm at different slope positions as sampling sites. the soil saples were collected from two depths of soil horizons to indicate cec, soil texture, oc%, calcium carbonate equivalent, x-ray diffract...
