“…However, no statistically significant correlation between K and P uptake by crops and their contents in soils was observed at any site. Our findings are consistent with Vanden Nest et al (2014) and Zörb et al (2014).…”

The effect of organic, mineral and combined organic and mineral fertilization of soils on the winter wheat yields and nutrient contents in soils was evaluated in long-term field experiments. Two sites with different soil characteristics were evaluated -Lukavec u Pacova (cambisol) and Ivanovice na Hané (degraded chernozem). The type of fertilization influenced wheat yields. Nutrient uptake by winter wheat was higher under nitrogen (N) fertilization, which resulted in a negative balance of phosphorus (P) and potassium (K) and to a decrease of nutrient contents in the more fertile soils at Ivanovice na Hané. Two soil tests (Mehlich 3 method and NH 4 -acetate method) were used to determine P and K availability. The mineral nitrogen fertilization negatively and significantly affected NH 4 -acetate extractable concentrations of nutrients in the soils and these were lower in comparison with concentrations of P and K determined by Mehlich 3 method. Relative availability of P in alkaline soils from Ivanovice treated with mineral N increased while the soil pH decreased.

“…Because of its pivotal role in turgor, primary metabolite generation and long-distance transport processes, K is a key component in mechanisms providing tolerance to drought, salinity, high brightness and cold, as well as to pathogens and pest insects. Despite its importance in these and other vital processes, there has not been strong interest in breeding to increase uptake and efficient use of this element, which requires rethinking the study objectives of various working groups in the world and prioritizing research on K as a key macronutrient in soil fertility and food security (Zörb et al 2014).…”

“…Some species of microorganisms, including Pseudomonas spp., Burkholderia spp., Acidithiobacillus ferrooxidans, Bacillus mucilaginosus, Bacillus edaphicus and Bacillus megaterium, have the ability to release K from materials containing this element by exudation of organic acids (Zörb et al 2014). These acids directly dissolve the K contained in rock minerals or chelate the primary ions contained in the minerals to release K (Basak and Biswas 2009).…”

Plant and microbe genomics and beyond: potential for developing a novel molecular plant nutrition approach

Classical soil science approaches have enabled us to establish basic principles of how the soil system functions and have answered numerous practical agricultural application questions. In recent years, efforts have been refocused on better understanding, managing and benefiting from this system that contains one of the most complex biological communities of the planet. Soil biology is seen as being at the center of scientific research of this century, with novel research objectives and goals being set. In addition, plant nutrition has enabled us to understand nutrient uptake, transport and mobilization mechanisms in plants, and both disciplines have converged on the area of microorganism-mediated plant nutrition. The challenge for these scientific areas is to identify microorganism communities and the roles they play in their habitats, as well as the mechanisms that plants have to make better use of nutrients. Genomics and metagenomics, along with microbiological techniques, are contributing greatly to advances in our understanding of living systems that exist in the soil and their interaction with plants. For its part, molecular plant nutrition has made significant progress in understanding the use of nutrients by plant cells, and has identified molecular mechanisms that can improve nutrient use efficiency. Together, molecular soil microbiology and molecular plant nutrition are projected to be a driving force in agriculture and sustainable food production in the coming years. Herewith, we aim to integrate recent literature on basic and applied research concerning plant and microbe genomics in terms of their potential for developing a novel molecular plant nutrition approach, with special emphasis on nitrogen, potassium and phosphorous as the major macronutrients for crop plants.
