Aboveground to root biomass ratios in pea and vetch after treatment with organic fertilizer
Some growth parameters of pea (cv. Pleven 4) and vetch (cv. Obrazets 666) after treatment with organic fertilizer were studied in a field trial carried out at the Institute of Forage Crops, Pleven, Bulgaria. Humustim as organic fertilizer was applied through presowing treatment of seeds, treatment during vegetation and combination between both, at different doses. Ratios of aboveground weight to ...

Nitrate leaching from a potato field using adaptive network-based fuzzy inference system
The conventional methods of application of nitrogen fertilizers might be responsible for the increased nitrate concentration in groundwater of areas dominated by irrigated agriculture. Appropriate water and nutrient management strategies are required to minimize groundwater pollution and to maximize nutrient use efficiency and production. Design and operation of a drip fertigation system ...

Assessment of climate change impact on crop yield and irrigation water requirement of two major cereal crops (rice and wheat) in Bhaktapur district, Nepal
Rice and wheat are major cereal crops in Nepal. Climate change impacts are widespread and farmers in developing countries like Nepal are among the most vulnerable. A study was carried out to assess the impact of climate change on yield and irrigation water requirement of these cereal crops in Bhaktapur, Nepal. Laboratory and soil-plant-air-water analysis showed silt-loam being the most ...

8 Main Points of Aquatic Plant Trimming (2)
5. Carbon dioxide should be increased after trimmingCarbon dioxide is the material basis for photosynthesis of aquatic plants and protects aquatic plants under strong light. After trimming, on the one hand, the lighting of the water grass is suddenly improved (the lamps have not changed, but the occlusion has been reduced, which is equivalent to increasing the lighting intensity). On the other ...

Root feeding of plants in the conditions of No-Till technology
About 6.5 million hectares of agricultural land in Ukraine are either degraded or unproductive. Above mentioned data are provided by the Food and Agriculture Organization of the United Nations. According to the opinion of other experts, impoverished soils occupy much bigger area and consist about 15 million hectares. The decrease in the amount of humus and the general deterioration of land is ...

Injection method of fertilization (Cultan technology)
Dosage of liquid fertilizers Liquid mineral fertilizers have already proven their advantages over granular fertilizers, these namely are prolonged action and maximum absorption of the active substance. So here is the question, what is the most effective way of using liquid fertilizers? Taking into consideration the reasons for transition to soil fertilizers, agronomists and farmers often point ...

Modeling the impact of nitrate fertilizers on groundwater quality in the southern part of the Nile Delta, Egypt
The use of fertilizers in agriculture in Egypt, especially nitrogen, has increased significantly in the last decade, resulting in nonpoint contamination of the groundwater resources. This study investigated the effect of using nitrogen fertilizer on groundwater contamination with nitrate in the central southern part of the Nile Delta. NO3− concentrations in shallow groundwater were assessed ...
