Effects of different doses of ammonium nitrate applications on nutrient content in some types of grass: nutritional support

This study was conducted under ecological conditions of Çanakkale (Turkey) province to investigate the effects of different ammonium nitrate (33% N) dose (0, 50 and 100 g m-2) on nitrogen, protein, macro-micro nutrient analyses of 3 different commonly cultivated grass varieties (Lolium perenne TOPGUN, Festuca rubra SERGEİ and Poa pratensis AVALANCHE). Plant nitrogen-protein analyses (nitrogen, protein) were determined besides plant macro-micro nutrient analyses (phosphorus, potassium, calcium, magnesium, ıron, manganese) of grass plants were determined. In the study, in addition to having information about the mineral content of grass species removed from the soil, the potential of the cuttings, which are formed when the grass plants are mowed, when used as green manure or compost has been determined.Fertilizer treatments increased nitrogen, phosphorus, potassium and protein contents of grass clippings and decreased calcium, iron, magnesium and manganese contents. In general, it was determined that the application of ammonium nitrate (33% N) at a dose of 100 g m-2 increased the nitrogen, protein, phosphorus and potassium amounts of plants compared to the application of ammonium nitrate (33% N) at a dose of 50 g m-2. Especially nitrogen phosphorus potassium fertilizers are among the fertilizers applied in intensive amounts in the agricultural sector. It is seen that nitrogen-containing ammonium nitrate fertilizer applied to grass plants increases the nitrogen content of grass plants. When the results of the study were examined, important information was obtained about how the fertilization density affects the nutrient content of the grass plants according to the species.
