Synopsis (short abstract) We introduce NPKGRIDS, a new geospatial dataset, providing for the first time data on application rates for all three main plant nutrients, nitrogen (N), phosphorus (P, in terms of phosphorus pentoxide, P2O5) and potassium (K, in terms of potassium oxide, K2O) across 173 crops as of 2020, with a geospatial resolution of 0.05° (approximately 5.6 km at the equator). Development of NPKGRIDS adopted a data fusion approach to integrate crop mask information with eight published datasets of fertilizer application rates, compiled from either georeferenced data or national and subnational statistics. Furthermore, the total applied mass of N, P2O5, and K2O were benchmarked against the country level information from FAO and the International Fertilizers Association (IFA) and validated against data available from National Statistical Offices (NSOs). NPKGRIDS can be used in global modelling, and decision and policy making to help maximize crop yields while reducing environmental impacts.

    CROPGRIDS: a global geo-referenced dataset of 173 crops 2024
    Also available in:
    No results found.
    CROPGRIDS is a comprehensive global geo-referenced dataset providing area information for 173 crops for the year 2020, at a resolution of 0.05° (about 5.6 km at the equator). It represents a major update of the Monfreda et al. (2008) dataset (hereafter MRF), the most widely used geospatial dataset previously available, covering 175 crops with reference year 2000 at 10 km spatial resolution. CROPGRIDS builds on information originally provided in MRF and expands it using 27 selected published gridded datasets, subnational data of 52 countries obtained from National Statistical Offices, and the 2020 national-level statistics from FAOSTAT, providing more recent harvested and crop (physical) areas for 173 crops at regional, national, and global levels. The CROPGRIDS data advance the current state of knowledge on the spatial distribution of crops, providing useful inputs for modelling studies and sustainability analyses relevant to national and international processes.

    No results found.
    This study examines the use of plant nutrients on individual crops in different regions of Poland in the context of the agro-ecological conditions, the structure of agriculture, the production and consumption of mineral and organic plant nutrients, the relationship between nutrient inputs and outputs, the need for mineral nutrients and the economics of fertilization.

    Fertilizer use by crop in Cuba 2003
    Also available in:
    No results found.
    In this study the agro-ecological structure and the areas, yields and fertilization of the individual crops in Cuba are examined. All Cuba’s fertilizer requirements are imported and the quantities available are limited. The use of fertilizers fell by 80 percent during the 1990s and the present level is insufficient to maintain yields and soil fertility. In order to alleviate the situation the Government gives priority to certain key crops such as sugar cane because of its economic importance and potatoes as a key food crop. The use of plant nutrients from organic sources is encouraged. The use of biofertilizers has been tried but only nitrogen-fixing Rhizobium has maintained its position.
