Variable-Rate Fertilization in a Custard Apple (Annona squamosa L.) Orchard Based On the Spatial Variability of Soil Nutrients
Due to the soil nutrient distribution caused by complex mountain topography, it is difficult to achieve the precise fertilization. This study...
-
Spatial Variability of NDVI and SPAD for Variable- and Fixed-Rate Fertilization in Olive Orchards
The aim of this study was to determine the spatial variability of fertilization requirements by using normalized difference vegetation index (NDVI)...
-
Evaluation of different crop model-based approaches for variable rate nitrogen fertilization in winter wheat
Several remote sensing-based methods have been developed to apply site-specific nitrogen (N) fertilization in crops. They consider spatial and...

N-fertilization and disturbance exert long-lasting complex legacies on subarctic ecosystems
Subarctic ecosystems are subjected to increasing nitrogen (N) enrichment and disturbances that induce particularly strong effects on plant...

Development of a Multi-Fertilizer Spreader Machine and Variable Rate Controller for Olive Orchards
The objective of this research was to develop a machine to spread three different mineral fertilizers at the same time at a variable rate if...

Effects of N-fertilization and Off-season Crops on Soybean Yield and Grain Protein and Oil Concentrations in a Tropical Climate
In the no-tillage system in Brazil, grasses are commonly grown for grain production or soil cover in the soybean off-season with no or low nitrogen...

Alternations in the element stoichiometry of the grasses drive the aboveground C:N:P ratio of an agriculturally improved pasture on karst in response to differential N and P fertilization
Background and aimsImbalances in nitrogen (N) and phosphorus (P) inputs in grasslands, induced by human activities, can significantly alter the C:N:P...

Phosphorus-based variable rate manure application in wheat and barley
Manure is used as a source of nutrients and organic matter for agricultural lands, but its unbalanced use has unfortunately made nitrogen (N) and...

Contrasting priming effect intensities and drivers in single and repeated glucose additions to a forest soil receiving long-term N fertilization
Soil nitrogen (N) availability plays an important role in regulating priming effects (PE). In this study, we aimed to investigate the effects of...

Soil respiration under different N fertilization and irrigation regimes in Bengaluru, S-India
Rapid urbanization in many countries of the Global South has led to intensification of urban and peri-urban agriculture (UPA) whose effects on the...
-
Nitrogen fertilization increased grass litter decomposition in a tropical agroforestry system
Litter decomposition and livestock excreta are two important sources for replenishing nutrients in the soil of the pastures, and their decomposition...
-
Management zone-specific N mineralization rate estimation in unamended soil
An ideal and efficient nitrogen (N) recommendation for precision fertilization (PF) should account for potential soil mineralizable N. This study...
-
Within-field spatial variability and potential for profitability of variable rate applications
Since literature is not unanimous about profitability of variable rate application (VRA), a systematic analysis is essential to determine when, where...

Long-term response of soil and stem wood properties to repeated nitrogen fertilization in a N-limited Scots pine stand
Nitrogen is the nutrient mainly limiting forest growth on mineral soil sites in the boreal regions. The objective of this study was to find out the...
-
Piscivorous bird assemblages at functional rather than species level better predict predation risk on open culture fish ponds within enhanced fertilization treatment regime
This study explored how increased water turbidity in open-aquaculture ponds as a result of enhanced fertilization influences piscivorous bird...

Nitrogen fertilization with pig slurry in a barley-sorghum double-annual forage cropping system
The high concentration of pig farms in NE Spain makes pig slurries an attractive fertilizer to reduce costs of agricultural production. However,...
-
Ammonium Nitrate Fertilization Increases the Crude Protein Content and Wheat Grain Yield in Subtropical Conditions
The objective was to evaluate the relationship between yield components, quality and estimated grain yield of wheat under ammoniacal and nitric...
-
Soil respiration and N-mineralization processes in the Patagonian steppe are more responsive to fertilization than to experimental precipitation increase
PurposeSoil respiration and N-mineralization are key processes in C and N cycling of terrestrial ecosystems. Both processes are limited by soil...
-
How Organic Acids Affect Plant Nitrogen and Phosphorus Uptake Under Different Fertilization Treatments
This study aimed to investigate the role of organic acids in the nitrogen (N) and phosphorus (P) nutrient dynamics of lemon plants by examining the...
