Micronutrients in soil "Hunger"

Li Rong, Director of the Soil and Fertilizer Quality Monitoring Division at the National Agricultural Technology Extension Service Center of the Ministry of Agriculture, pointed out that the extensive use of fertilizers containing the three major elements—nitrogen, phosphorus, and potassium—has led to an increasingly severe imbalance in the soil’s macronutrients—calcium, magnesium, and sulfur—and micronutrients—including zinc, copper, iron, molybdenum, manganese, and boron. According to the survey, our country... Approximately 85% of cultivated land suffers from a severe deficiency of meso- and trace elements, making it imperative to promptly replenish these elements in the soil.

gamma - Gamma-aminobutyric acid ( GABA ) Significantly promotes the absorption of meso- and trace elements.

3. MPA, EGTA, and TFP can directly or indirectly inhibit endogenous GABA synthesis. As shown in the figure, exogenous GABA can compensate for the deficiency of endogenous GABA, thereby triggering Ca²⁺ influx. Ca²⁺ is an important regulatory messenger in rapidly growing pollen tubes, and GABA regulates the flow of calcium ions to modulate the polar growth of pollen tubes.

Hanhe Biology GABA Promotes Magnesium, Calcium, and Boron Absorption: Test Report

Calcium and boron are both elements that are poorly mobile within plants, and... GABA can serve as a potential regulator of ion transport, promoting the accumulation of mineral elements in plant tissues. In this study, we compared the effects of applying calcium-magnesium-boron products with those of calcium-magnesium-boron products supplemented with GABA. We measured the magnesium, calcium, and boron contents in the aerial parts of pak choi 24 hours after foliar fertilization, aiming to investigate the impact of GABA on pak choi’s uptake of magnesium, calcium, and boron.

1. Test Method

2 Experimental results

3, Results Analysis and Discussion

( 1) Within 24 hours after foliar spray, Magnesium-Calcium-Boron No. 1 significantly promotes the uptake of magnesium by the aerial parts of pak choi, and extremely significantly promotes the uptake of boron; its effect on calcium uptake is not obvious. Magnesium-Calcium-Boron No. 2 (with added GABA) extremely significantly promotes the uptake of both magnesium and boron by the aerial parts of pak choi, and significantly promotes the uptake of calcium.

( 2) Within 24 hours after foliar spray, compared to Magnesium-Calcium-Boron No. 1, Magnesium-Calcium-Boron No. 2 (with added GABA) significantly promotes the uptake of magnesium by the aerial parts of pak choi, markedly enhances calcium uptake, and significantly reduces boron uptake.

Reeve and Shive found that calcium application exacerbates boron deficiency symptoms in tomatoes. Since 50% of boron and 70% of calcium are concentrated in the cell walls, when either boron or calcium is deficient, growth points often exhibit similar deficiency symptoms. Moreover, an increase in one of these elements can inhibit the plant's uptake of the other. Based on these findings, the results of this experiment are consistent with those reported by Reeve and Shive: even when pak choi has sufficient calcium and magnesium levels, its boron uptake is still affected—this phenomenon may be related to differences in crop characteristics and growth stages. Through extensive experimental verification, it has been confirmed that GABA indeed participates in the ion transport mechanisms within plants and significantly enhances the absorption of key elements, thereby achieving the effects of increased yield and improved product quality.

Continuous technological innovation is helping to develop better and more stable efficiency-enhancing fertilizers.
