Early fertilizer nitrogen (N) application on cover crops or their residues during the off-season is a practice adopted in Brazil subtropical conditions under no-tillage corn (Zea mays L.) systems. However, the effect of early N application on yield, plant N content, and N recovery efficiency (NRE) for corn is not yet well documented. Five fertilizer N timings in an oat-corn system were ev…
Background and Aims: Phosphate (Pi) is one of the most limiting nutrients for agricultural production in Brazilian soils due to low soil Pi concentrations and rapid fixation of fertilizer Pi by adsorption to oxidic minerals and/or precipitation by iron and aluminum ions. The objectives of this study were to quantify phosphorus (P) uptake and use efficiency in cultivars of the species Coff…
Nitrogen is the nutrient required in greatest quantity by the coffee and the second most exported by the plant, being fundamental in the synthesis of various compounds. Usually apply urea in coffee and N from this source is rapidly metabolized and incorporated in amino acids and amides. The assimilation of N is affected by several micronutrients, including nickel (Ni), due to it is a cons…

Due to the great heterogeneity of soils around the world, the availability of nutrients appears as an important limiting factor for plant productivity in agricultural and forestry systems. The low availability of these nutrients in the soil, especially phosphorus, leads to significant ontogenetic and metabolic changes of the root system, which will affect the deposition of biomass between…
Soybean (Glycine max (L) Merrill) is the most sown crop in Brazil today, and its productivity increased by about 72% between 1973 and 2015. This increase is due to new agricultural technologies and management, and to the genetic gain provided by plant breeding. Several studies in soybean-producing countries have evaluated the physiological changes that occurred in their cultivars; however…
The reproductive phase of the coffee tree is associated with a new vegetative cycle. Thus, coffee needs to deal with two simultaneous demands of mineral substances: the need for fruiting plus the need for annual vegetative growth. However, a method to estimate the annual vegetative biomass increment is not yet known. What is the reason for this concern? This is due to the fact that the of…

Plants alter their metabolism in order to coordinate the communication between aerial and underground parts to achieve the best allocation of resources and sustain plant growth and productivity. Moreover, the plant nutritional status and external availability of nutrients will modulate the three-dimensional arrangement of root development, its growth, and, therefore, the entire plant meta…
Nickel (Ni) has been regarded as essential micronutrient for plants to be a constituent of the active site of the enzyme urease, which hydrolyzes urea to ammonia and bicarbonate. The urease protein is abundant in seeds of some plant species and is also found at low levels in vegetative tissues of many, if not all, plants. A deficiency of this enzyme leads to accumulation of urea and subse…
