Nutrient elements are important for plant growth. Element stoichiometry considers the balance between different nutrients and how this balance is affected by the environment. So far, focus of plant stoichiometry has mainly been on the three elements carbon (C), nitrogen (N), and phosphorus (P), but many additional elements are essential for proper plant growth. Our overall aim is to test the scaling relations of various additional elements (K, Ca, Mg, S, Cu, Zn, Fe, Mn), by using ten data sets from a range of plant functional types and environmental conditions. To simultaneously handle more than one element, we define a stoichiometric niche volume as the volume of an abstract multidimensional shape in n dimensions, with the n sides of this shape defined by the plant properties in question, here their element concentrations. Thus, a stoichiometric niche volume is here defined as the product of element concentrations. The volumes of N and P (V NP ) are used as the basis, and we investigate how the volume of other elements (V Oth ) scales with respect to V NP¸w ith the intention to explore if the concentrations of other elements increase faster (scaling exponent > 1) or slower (<1) than the concentrations of N and P. For example, scaling exponents >1 suggest that favorable conditions for plant growth, i.e., environments rich in N and P, may require proportionally higher uptake of other essential elements than poor conditions. We show that the scaling exponent is rather insensitive to environmental conditions or species and ranges from -3.804 to 1.976 (average 0.384) in nine out of ten data sets. For single elements,Mg has the smallest scaling exponent (0.524) and Mn the largest (2.666). In two of the ten data sets the scaling exponent is negative but positive in the other eight sets. Comparison between laboratory determined stoichiometric relations and field observations suggest that element uptake in field conditions often exceeds the minimal physiological requirements. The results provide evidence for the view that the scaling relations previously reported for N and P can be extended to other elements; and that N and P are the driving elements in plant stoichiometric relations. The stoichiometric niche volumes defined here could be used to predict plant performances in different environments.

“…These data indicate that, regardless of fertilization treatment, there was more N, P and Mg in wheat grain than in straw, while there was more K, Na and Ca in straw than in grain. Studies by Hamner et al [37] confirm that more N, P and Mg is accumulated in grains of cereals than in straw. Studies by Matraszek et al [38] as well as Doltra et al [39] also confirm that cereal straw contains more K and Na, and when this plant part is intended for energy purposes, the above-mentioned elements can accelerate corrosion of biomass burning boilers [40].…”

“…Chemical composition of plants is an important index of yield quality [37,38]. It is assumed that good quality feed should contain approximately 7-18 g N, 1.7-4.5 g P, 6.0-12 g K, 2-8 g Ca, 1-2.5 g Mg, and 1.5-2.5 g Na/kg d.m.…”

Municipal sewage sludge from rural sewage treatment plants is characterized by a substantial content of organic matter and macronutrients, which can be used in cultivation of cereals. In a farm located in the commune of Iwanowice in the south of Poland (Malopolska province), municipal sewage sludge was applied under spring wheat cultivation. The experiment was set up on heavy soil with slightly acid reaction and medium content of available forms of P, K, Mg. Application of sewage sludge in a dose of 23 Mg fresh matter per hectare (4.21 Mg d.m.) led to no significant changes in chemical properties of the soil. Application of sewage sludge significantly increased yield of spring wheat. That increase led to a significant decrease in the content of N, P, K, Na, Mg and Ca in spring wheat. Utilization of N, Mg, K, P and Ca from sewage sludge by spring wheat was at a level of 82, 63, 44, 36, 9 %, respectively, of the amount introduced with the waste. Application of municipal sewage sludge significantly decreased the value of Ca : P ratio in spring wheat grain and straw. The sewage sludge did not cause a significant change in the values of Ca : Mg, K : Na, K : (Ca+Mg), K : Mg and K : Ca ratios in spring wheat grain and straw. Municipal sewage sludge can be used environmentally, including for fertilization of cereals, provided that environmental standards are kept.

Nitrogen is a component of proteins contained in grains and potassium an enzymatic activator in nitrate (NO3-) assimilation and contributes to the translocation and storage of plant assimilates. Together they can increase protein contents of wheat grains. This research aimed to evaluate whether the interaction between nitrogen (N) and potassium (K) fertilizations in irrigated wheat in the Cerrado region of the Mato Grosso State increases the content and accumulation of N, K, and protein in wheat grains. The experiment was carried out in the field for two consecutive years (2014 and 2015) in the Federal University of Mato Grosso. It was designed in randomized blocks in 52 fractional factorial, composed of combinations between five doses of each of N and K, 13 treatments combinations in total with four replicates. After harvest, the grains were dried to determine the contents of N, K, and protein. The nitrogen content was influenced by nitrogen doses in both years and the accumulation significantly influenced by the nitrogen and potassium doses with an average increase among the years of 55.29% as a function of the potassium application. Nitrogen influenced the accumulation of potassium only in 2015 with effect for potassium in both years. Although there was no interaction between treatments, the influence of K on N absorption was evident. Contents and accumulations of N and K and the content of protein in wheat grains are influenced by N and K fertilizations.
