“…Research shows that chemical clogging could be relieved by enhancing the acidity of irrigation water or using acidified fertilizers [ 17 , 18 ]. Due to its strong acidizing effect, hydrochloric or nitric acid has also been considered as an effective additive for eliminating the phenomena [ 19 , 20 ]. However, both chemical acidification and long-term application of acidic fertilizers will cause harm to crop and soil, as well as corrosion of drip irrigation equipment.…”

Biochemical fulvic acid (BFA), produced by organic wastes composting, is the complex organic matter with various functional groups. A novel modified biochemical fulvic acid (MBFA) which possessed stronger chelating ability had been synthesized by the grafting copolymerization of BFA and acrylic acid (AA). Results showed that MBFA effectively inhibited the crystallization of calcium phosphate and increased the concentration of phosphate in water solution. The optimum reaction conditions optimized by Box–Behnken design and response surface methodology were reaction temperature 69.24 °C, the mass of monomer to fulvic acid ratio 0.713, the initiator dosage 19.78%, and phosphate crystal-inhibition extent was 96.89%. IR spectra demonstrated AA was grafted onto BFA. XRD data and SEM images appeared the formation and growth of calcium phosphate crystals was effectively inhibited by MBFA.

“…Solutions for sustainable fertilizer management should take into account that farmers do not always have the technical skills for estimating accurately fertilization rates. The complex technical framework for current fertilization, its integration with other management practices, and specific needs of final users were highlighted by Peragón et al (2017) as crucial issues in the development of decision-making tools targeted at fertilizer management. Specific software has been developed for fertilizer management.…”

Rational fertilizer management is crucial in the efficient use of resources that are basically non-renewable and that can have a great environmental impact when used without scientific basis. The availability of scientifically sound decision-making tools for rational fertilization is scarce. We have developed a Windows program to calculate the required seasonal N, P and K rates, and the most cost-effective combination of commercial fertilizers. The tool also provides estimates of the Ca, Mg and S balances in the field resulting from the fertilizer program chosen. Novel aspects of the calculations include the development of stochastic flexible fertilizer programs for N and the calculation of acidification and N losses. Regarding P and K, estimations are provided on the grounds of threshold values of usual availability indexes, something frequently unknown by final users. Also, it allows the users to determine the best complex fertilizer for pre-plant applications to avoid blending of simple fertilizers at the farm, a task usually complex for farmers. The application may be useful both to the fertilizer supply and demand sides. In addition, it may be used for teaching as it helps understanding the rationale behind this management practice.
