C. de C. aNutrient use efficiency in agricultural systemsba brazilian perspective.h[electronic resource] c2024 ap. 52-53. aMost Brazilian soils are deep, highly weathered, acidic, and of low natural fertility. Many strategies have been developed for building soil fertility using lime and mineral fertilizers, particularly phosphorus (P), potassium (K), and micronutrients to attain higher yields. Brazil currently uses 8% of all the fertilizer produced in the world. The country is fourth among the largest consumers, behind only China, India and the United States. However, there is a big problem: national production is minimal. More than 85% of nutrient sources are imported to meet agricultural demand. aFertilizers aPrecision agriculture aSoil analysis aEnhanced efficiency fertilizers aILPF aIntegrated systems tFertilizer Focusgv. 41, n. 1, jan./feb. 2024.
