This research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. This experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of Chenran Township. The results ...

The objective of this study is to present a new application of optical and radar remote sensing with high spatial ( 10 m) and temporal (a few days) resolutions for the detection of tillage and irrigation operations. The analysis was performed for irrigated wheat crops in the semi-arid Tensift/Marrakech plain (Central Morocco) using three FORMOSAT-2 images and two ASAR images acquired within one...

Agricultural development in sub-Saharan Africa faces daunting challenges, which climate change and increasing climate variability will compound in vulnerable areas. The impacts of a changing climate on agricultural production in a world that warms by 4°C or more are likely to be severe in places. The livelihoods of many croppers and livestock keepers in Africa are associated with diversity of o...

introduction the global climate is changing and, despite efforts to reduce greenhouse gas emissions, weather variation is inevitable. meanwhile, agriculture as a major water consumer will require adaptation to these variations, along with other challenges, to guarantee its persistence and sustainability. given the arid and semi-arid climate of iran, water, as a main limiting factor for agricult...

The WSN(Wireless Sensor Networks) technology is one of the important technologies to implement the ubiquitous society, and it could make many changes in the existing agricultural environment including livestock rearing, cultivation and harvest of agricultural products if such a WSN technology is applied to the agricultural sector. This study attempts to establish ubiquitous agricultural environ...

Abbreviations and Notes: N = nitrogen; P = phosphorus; K = potassium; Ca = calcium; Fe = iron; Si = silicon. The Origins of Biodynamic Agriculture Biodynamics is system of agricultural management based on a series of lectures given by Rudolf Steiner in 1924. A philosopher by training, Steiner sought to infl uence organic life on earth through cosmic and terrestrial forces via nine preparations ...

crop rotation is one of the essential practices in sustainable agricultural systems, be-cause of its effects on soil fertility and other benefits including a reduction in weed compe-tition. a field experiment was conducted at chaparsar rice research station, tonekabon, iran, from 2002 to 2003 to assess the influence of crop rotation, time of planting, and till-age depth on rice (oryza sativa l....

Despite improvements in the use of soil conservation practices, crop rotation and nutrient management programs, significant concern still exists regarding soil erosion and nutrient losses in runoff from row crop production. In the US, states are required to implement water quality standards based on USEPA guidelines or other scientifically defensible methods (Ice and Binkley, 2003). Agroforestr...

The USDA established the National Organic Program (NOP) to develop national standards for organically produced agricultural products and establish an organic certification program as required by the Organic Foods Production Act (OFPA) passed by Congress in 1990. Organic crop production excludes conventional pesticides, petroleum – based fertilizers, and sewage sludge based fertilizers with some...
