optimization of land allocation in golestan province for planting agricultural crops using compromise mathematical programming introduction: rational planning and optimization of agriculture are essential because of water and land constraints, the need to increase economic profit and to reduce the negative impacts of fertilizers and pesticides. to this end, decision-makers and planners need to ...

this experiment was conducted in order to optimize the use of paddy fields as second cropping in the mazandaran province. study planed with 8 new cultivars and carried out in randomized complete block design with four replications during two years 2006 and 2007 in dashte-naz agricultural research station of sari. nursery prepared in the september and seedlings were transferred to the field in t...

We studied the impacts of anthropogenic changes in land use on the stoichiometric imbalance of soil carbon (C), nitrogen (N), phosphorus (P) and potassium (K) in Phragmites australis wetlands in the Minjiang River estuary. We compared five areas with different land uses: P. australis wetland (control), grassland, a mudskipper breeding flat, pond aquaculture and rice cropland. Human activity has...

Unpredictable conditions of rice cultivation on fragile peatlands in Indonesia due to land-use changes would be an obstacle agricultural food production and security. This study aimed determine the land usage Bengkulu, from prospective fields oil palm plantations. The was conducted June October 2020 at Air Manjuto irrigation paddy Mukomuko Regency, Bengkulu Province. analysis used satellite ima...

Soil pollution and crop contamination by cadmium (Cd) and Arsenic (As) are widely-known and recognized as a global threat to sustainable life and the environment. Various factors contribute to soil pollution, including pollutants factor: sources of pollutants, pollutant pathways, the medium of pollution, and soil factor. Japanese agricultural soils in some region, have been heavily polluted wit...

regional impact studies of the future climate change effects are necessary because projected changes in meteorological variables differ from one region to another, and different climate systems can react in varied ways to the same changes. in this study, the effects of climate change on bioclimatic deficiency were compared in two cultivation methods (irrigated and rainfed) in a semi-arid region...

Abstract Decadal changes in land use/land cover for Balachaur watershed in Nawanshahar district, Punjab, India were studied using black and white aerial photographs for March 1984 on approximately 1:20,000 scale and multidate geocoded false colour composites (FCC) of IRS-1D LISS-III on 1:50,000 scale for March 2002, September 2002, and May 2003 and interpreted visually to prepare land use/land...

In this paper, we developed a more sophisticated method for detection and estimation of mixed paddy rice agriculture from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data. Previous research demonstrated thatMODIS data can be used tomap paddy rice fields and to distinguish rice from other crops at large, continental scaleswith combined Enhanced Vegetation Index (EVI) and Land...
