Nitrogen (N), phosphorus (P), sulfur (S), zinc (Zn), and iron (Fe) are some of the vital nutrients required for optimum growth, development, and productivity of plants. The deficiency of any of these nutrients may lead to defects in plant growth and decreased productivity. Plant responses to the deficiency of N, P, S, Fe, or Zn have been studied mainly as a separate event, and only a few reports discuss the molecular basis of biological interaction among the nutrients. Macro-nutrients like N, P, and/or S not only show the interacting pathways for each other but also affect micro-nutrient pathways. Limited reports are available on the investigation of two-by-two or multi-level nutrient interactions in plants. Such studies on the nutrient interaction pathways suggest that an MYB-like transcription factor, phosphate starvation response 1 (PHR1), acts as a master regulator of N, P, S, Fe, and Zn homeostasis. Similarly, light-responsive transcription factors were identified to be involved in modulating nutrient responses in Arabidopsis. This review focuses on the recent advances in our understanding of how plants coordinate the acquisition, transport, signaling, and interacting pathways for N, P, S, Fe, and Zn nutrition at the molecular level. Identification of the important candidate genes for interactions between N, P, S, Fe, and/or Zn metabolic pathways might be useful for the breeders to improve nutrient use efficiency and yield/quality of crop plants. Integrated studies on pathways interactions/cross-talks between macro‐ and micro-nutrients in the agronomically important crop plants would be essential for sustainable agriculture around the globe, particularly under the changing climatic conditions.

Understanding plant nutrition can be the difference between vigorous, productive plants and plants that struggle. You may be familiar with the macronutrients like nitrogen or potassium. These are the most commonly discussed nutrients since they are needed in the largest amounts.However, they aren’t the only essential nutrients that your plants need. Your plants will also need micronutrients in order to thrive.

Western Canadian crops require 17 essential nutrients to grow normally. Carbon, hydrogen, and oxygen derived from the air comprise more than 90 per cent of the fresh plant tissue. Macronutrients derived from the soil and needed in large amounts are nitrogen (N), phosphorus (P), potassium (K), sulphur (S), calcium (Ca), and magnesium (Mg). Legumes are the exception because they fix N from the air. With a few exceptions, Ca and Mg are not limiting in Saskatchewan because of the nature of the soils. The soil supply of N, P, K, and S is often supplemented by fertilizer and manure.The remaining essential nutrients derived from the soil are referred to as micronutrients, because they are needed in small amounts. They are boron (B), chloride (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni) and zinc (Zn). Micronutrients are important for plant growth, as plants require a proper balance of all the essential nutrients for normal growth and optimum yield.

Polyaspartic acid sodium salt is a water-soluble polymer. It is a green water treatment agent with properties of non-phosphor, non-nitrogen, non-pollution, and fully biodegradation.

PASP is a kind of biopolymer materials, of which molecules contains abundant amido bond, carboxyl and other active groups. Amido peptide bond has biological activity and high chemical stability, hard to decompose at high temperature; carboxyl group can be complex with many metal ions in water, which make PASP have high chemical activity in aqueous solution; in each structural unit of PASP, the oxygen and nitrogen atoms can easily form hydrogen bonds with water molecules, it has good hydrophilicity and water solubility. The special molecular structure of PASP ensures that it has good dispersing ability, corrosion inhibiting properties, excellent biodegradability and environmental friendly characteristics.

Given the clinical severity of the toxicities associated with aminoglycosides, a great deal of research has been devoted to the discovery of agents that can prevent these sequelae.
