In addition to the four groups of classic combinations mentioned above, mineral source potassium fulvic acid / humic acid can also be matched with the following five types of agricultural products to play a significant role in soil improvement, stress and disease prevention, precision fertilization and other scenarios, and further expand the planting application scenarios.
1、 Matching with microbial inoculants: soil improvement, bacteriostasis and disease prevention
The combination of mineral source potassium fulvic acid / potassium humate and microbial agents (such as Bacillus subtilis, Trichoderma harzianum, EM bacteria, etc.) is the “golden partner” of soil improvement. The mineral source potassium fulvic acid can provide sufficient carbon source and suitable living environment for the microbial flora, promote the rapid propagation of beneficial bacteria and enhance the activity of the flora; The metabolites produced during the growth of microbial agents can inhibit the breeding of pathogenic bacteria in the soil and reduce the occurrence of soil borne diseases. On the one hand, it can improve the soil aggregate structure, break the hardening, and enhance the ability of soil to retain water and fertilizer; On the other hand, it can activate the fixed phosphorus, calcium, magnesium and other medium and trace elements in the soil, while inhibiting harmful organisms such as root knot nematodes, so that crop roots can thrive in a healthy soil environment, especially suitable for continuous cropping plots and fields with serious soil degradation.
2、Matching with medium and trace elements fertilizer: Precise Fertilization to avoid lack of nutrients
When the mineral source potassium fulvic acid / potassium humic acid is combined with calcium, magnesium, zinc, iron, molybdenum and other medium and trace element fertilizers, the pain point of “fertilizer supplement is not absorbed” can be solved. Although the demand for medium and trace elements is small, they are essential for crop growth and development, but they are easy to be fixed by soil or antagonized with other elements, resulting in the inability of crops to absorb them efficiently. The key role of chelation of mineral source potassium fulvic acid is to convert medium and trace elements into stable chelated state, avoid their adsorption by soil colloids or chemical reaction failure, and extend the effective period of nutrients in the soil and promote the active absorption of crop roots. For example, matching with calcium fertilizer can prevent crop fruit cracking and umbilical rot; The combination with zinc fertilizer can alleviate the phenomenon of small leaf disease and stiff seedlings; The combination with iron fertilizer can improve the problem of leaf yellowing, make crops nutritionally balanced, grow steadily, and reduce the quality decline and yield loss caused by nutrient deficiency.
3、 With root stimulants: double root promotion and root burst growth
. Rooting agent can directly stimulate root cell division, promote main root elongation and lateral root germination; Mineral source potassium fulvic acid can strengthen root activity, improve the ability of root system to absorb water and nutrients, and protect the new root system from soil stress (such as saline alkali, drought). This combination is especially suitable for the use of crop seedling stage and transplanting stage, which can significantly improve the survival rate of transplanting, shorten the slow seedling stage, make the crop quickly establish a robust root system, and lay the foundation for subsequent high yield; It can also be used to recover crops with damaged roots (such as after fertilizer damage and Waterlogging Damage) and accelerate root regeneration.
4、 Matching with drought and stress resistors: enhancing resistance, stabilizing yield and ensuring harvest
Under extreme environments (drought, high temperature, low temperature, salt and alkali), the combination of mineral source potassium fulvic acid / potassium humic acid and drought and stress resistance agents (such as humic acid drought resistance agents, amino acid drought resistance agents, betaine, etc.) can significantly improve the stress resistance of crops. The mineral source potassium fulvic acid can regulate the osmotic pressure of crop cells, reduce water loss, strengthen leaf photosynthesis, and accumulate more stress resistant substances; . They work together: during drought, it can reduce crop wilting and prolong drought resistance time; At low temperature, it can protect crop cells from freezing injury and alleviate the inhibition of growth by chilling injury; Saline alkali soil can reduce soil salt concentration, reduce salt damage to roots, help crops grow normally in adversity, and ensure stable yield.
5、 Matching with organic fertilizer: improving quality and efficiency, and nourishing soil
The combination of mineral source potassium fulvic acid / potassium humic acid and organic fertilizers (such as decomposed farmyard manure, bio organic fertilizer, cake fertilizer, etc.) is an ideal combination of “fertile soil + efficient fertilization”. Organic fertilizer can supplement a large amount of organic matter to the soil and improve the physical and chemical properties of the soil, but the effect is slow; Mineral source potassium fulvic acid can accelerate the decomposition and maturity of organic fertilizer, promote the transformation of organic matter into nutrients that can be absorbed by crops, shorten the effective cycle, and improve the utilization rate of organic fertilizer. .
