Effect of Jellyfish fertilizer on Seedling Growth and Soil Properties
The excessive increase of jellyfish swarms could threaten the fishers and the marine food chain. The aim of research was to evaluate the potential benefit of the jellyfish as a fertilizer for different trees. The greenhouse experiment was conducted at Kutan, Chuncheon, South Korea using two tree species. Jellyfish was applied to soil before planting at different application rates (1.6, 2.7, 5.5...
متن کاملRevision of Potassium Soil-test Interpretations and Fertilizer Recommendations
There is a long history of potassium (K) fertilization research in the North-Central Region. Sustained Iowa field research efforts have focused on developing soil-test K (STK) interpretation and studying the effect of K fertilization strategies on grain yield and STK. Because of changes in the soil-test K method used in Iowa, information published over time should be evaluated separately. Publi...
متن کاملPredicting Soil Phosphorus Fertilizer Rate Using Hierarchical Segmented Regression Models
Predicting soil phosphorus (P) needs and P fertilizer requirements is important for plant nutrition and reducing environmental risk. The P requirement (PR) can be calculated from three components: the current status of soil P (P0), soil P buffer coefficient (PBC), and the soil P critical level (PCL). The PBC and PCL can be predicted from soil clay content using linear-plateau models. The PR, PB...

متن کاملSoil Amendments and Fertilizer Source Effects on Creeping Bentgrass Establishment, Soil Microbial Activity, Thatch, and Disease
Natural organic fertilizers require microbial degradation for nitrogen (N) release, but their ability to promote rapid turfgrass establishment has not been well documented in newly constructed sand-based rootzones. This 2-year field study evaluated the influence of two general fertilizer and soil amendment programs for their effect on establishment and quality of three creeping bentgrass (Agros...
