Roots serve a vital role (among other functions) in extracting water from the soil, transporting it to the shoot and sustaining transpiration. To fulfill this function, roots have a complex anatomical structure consisting of different cell layers with varying hydraulic conductivities. This composite structure offers different pathways for radial flow of water from the root surface towards xylem vessels: (i) the apoplastic pathway through the intercellular space and the cell wall; (ii) the symplastic pathway via plasmodesmata channels extending across neighboring cells; and (iii) the transcellular pathway which involves crossing membranes of neighboring cells. Pathways (ii and iii) are commonly referred to as the cell-to-cell pathway.

Roots are capable of varying the permeability of their cells and tissues to fulfill multi-facet functions, such as (i) transport of water and nutrients towards the xylem vessels; (ii) protection against desiccation in drying soils; and (iii) avoidance of leakage of nutrients and photosynthesized compounds into the soil.

Application of AG-SAP in topdressing a tree

Based on the projection of the canopy, dig a 20-30cm wide annular ditch or strip ditch along its projected edge, and the depth is based on the exposed part of the root system (about 30-50cm). Mix the water-retaining agent with fine soil or fertilizer evenly and then apply it. The middle and lower part of the ditch shall be filled with soil for irrigation. Application rate: for young trees: 20-80 g/plant; mature trees: 80-200g/plant.

It is suitable for apple, cherry, jujube, pear, peach, walnut and other fruit trees.

Application of AG-SAP in transplanting young trees

•Dip the roots

Mix the water-retaining agent and water in a ratio of 1:100-150 to make a gel, or add loess to make a slurry, soak the roots of the seedlings in the gel for 3-5 seconds, and plant them with the dip. For seedling transplanting, it is best to wrap the seedlings with plastic film when transporting them.

•Hole application

After mixing the water-retaining agent with most of the soil dug out of the tree hole, it is divided into two parts and applied into the tree hole. The first part is applied to the bottom of the hole. After placing the seedlings, the remaining mixed soil is backfilled, compacted and watered. It is suitable for transplanting fruit trees and saplings of green trees. Application rate: DBH 2-4cm: 20-30g/plant; DBH 4-5cm: 50-70g/plant; DBH 6-7cm: 80-100g/plant; adult tree: 100-200g/plant.

Application of AG-SAP in Turf

•Application in new turf

First mix the SAP with fine dry soil in a ratio of 1:5-10 and spread it evenly on the soil surface, then turn it into the soil layer about 5-10cm deep, then sow seeds or plant turf, and water it thoroughly. Application rate: sandy soil: 40-60g/ m2; loam soil: 20-40 g/ m2.

•Existing turf applications

First, dig up the turf in pieces and set it aside, spread a layer of SAP evenly on the soil surface under the turf (mix it with the fine dry soil), then plant the dug turf back to the original place, and then water it thoroughly. Application rate: sandy soil: 40-60g/ m2; loam soil: 20-40 g/ m2.

Dosage of AG-SAP in agricultural crops

1. Seed treatment

Mix seed with 0.5%-1.0% SAP water gel, and sow after drying.

2. Hole application

Mix the SAP and fine dry soil at a ratio of 1:5-10 (or mix with fertilizer), and evenly apply it into the planting hole with a depth of 10-20cm, then cover with soil and water, and the application rate: 30-75 kg/ Ha. It is suitable for tomato, pepper, watermelon, potato, sweet potato and other hole crops.

3. Ditching

Mix the SAP and fine dry soil in a ratio of 1:5-10 (or mix with fertilizer), and evenly apply it into a 10-20cm planting ditch. Application rate: 30-75 kg/ Ha. It is suitable for row crops such as flue-cured tobacco, peanut, rape, radish, wheat, cotton and sorghum.

4. Spray

Mix the SAP with fine dry soil (or mix with fertilizer) at a ratio of 1:5-10, spray it on the surface of the soil, and then turn it into the soil layer about 5-10cm deep, water it thoroughly, and then Sow the seeds. Application rate : 90-150 kg/Ha. Suitable for sowing crops such as lettuce and chrysanthemum.

AG-SAP to improve soil structure

Improve soil structure (agglomerate structure, water permeability, air permeability, heat capacity, etc.)

The repeated shrinkage and absorption of the water-retaining agent cause a large number of pores in the soil, improve the air permeability and water permeability of the soil, and improve the plant rhizosphere environment.

The decomposition of minerals is conducive to root absorption, promotes the growth and development of roots and plants, improves the soil matrix, and prevents soil compaction and salinization.

AG-SAP as water retention

The SAP is working as water-retaining agent and is applied to the root system of the plant.

After rainfall or irrigation, SAP absorbs and preserves the excess water in the soil, including water-soluble fertilizers, to form a large number of underground “mini-reservoirs”, which are slowly released when the plants need it.

In this way, it can not only ensure the water required for the normal growth of plants, but also prevent the water from being wasted due to evaporation, leakage and loss, and keep the soil moist for a long time.

It can absorb and release water repeatedly, which can be used by plants slowly.
