SAP application guidelines in crops & plants

I. Main points

● SAP shall be applied at the root.

● Don't expose SAP in the air.

● SAP can't make water, it is effective for drought-resistance only in the case of a small amount of water.

● If in dry method, watering thoroughly. If without watering condition, wet method is suggested.

● No matter in dry or wet application, SAP must be mixed evenly with ditch subsoil to avoid water excessive concentration that might cause rotten species or rot.

● This guideline is only for your reference. Due to the difference of regional soil, climate and drought conditions, application shall be based on the actual situation.

II. Main crops

1. For wheat, barley etc.

The dosage for dry powder is 1.5~3 kgs per Mu (i.e, 666.7M2). Application method as belows:

A: For basal application

1 ) Use dry method for moistly soil: mix SAP with 10 to 30 times dry fine soil then apply into the planting trench;

2) Use wet method for dry soil: make SAP to 200 times hydrogel (i.e, mix SAP with 200 times water), then apply into the planting trench, mix even with ditch soil, then sow the seeds in planting trench, water after casing to guarantee SAP in water stored state.ask me Skype:frank99886600

3) If in mechanical sowing, mix SAP with soil, thrown into the terraces with base fertilizer, watering immediately after sowing.

B: For seed dressing

Follow the instruction s to use as the case may be pre-seed dressing.The ratio of seeds, SAP and water is 100:1:100, i.e, 100kgs seeds need 1kg SAP and 100kgs water.ask me Skype:frank99886600

2. For maize

The dosage is 1.5~3kgs per Mu (i.e, 666.77M2). Application method as belows:

A: For basal application

1 ) Use dry method for moistly soil: mix SAP with 10 to 30 times dry fine soil then apply into the planting trench;

4) Use wet method for dry soil: make SAP to 200 times hydrogel, then apply into the planting trench, mix even with ditch soil, then sow the seeds in planting trench, water after casing to guarantee SAP in water stored state.

5) If in mechanical sowing, mix SAP with soil, thrown into the terraces with base fertilizer, watering immediately after sowing.

B: For seed dressing

Follow the instructions to use as the case may be pre-seed dressing.The ratio of seeds, SAP and water is 100:1:100, i.e, 100kgs seeds need 1kg SAP and 100kgs water.

*Application time:

a. Use dry method 5~10days earlier before the rainy season (absorb water in rainy season, release water in drought time).

b. Mix SAP with fertilizer in winter before or after picking the fruit or use wet method in spring fertilization.

c. 10~20 days earlier before spores germinating, apply for it just one time per year. Application method is the same as per the adult tree.

2) for young tea trees: 1.5~2kgs/ Mu (i.e, 666.77M2). Application time & method is the same as above.

3) for tea trees transplant: 2kgs/ Mu (i.e, 666.77M2), application method: dipping + basal application.

* Dipping: according to the instructions, dip the root and fix planting.

* Basal application:Skype:frank99886600 

a. dry method:

Sprinkle the dry powder into the ditch or hole (can put the fertilizer at the same time), mix even with ditch soil, transplant the seedling, casing into concave shape for collecting water, water immediately.

b. Wet method:

 

Make SAP to200 times hydrogel and put into the ditch or hole ( can put the fertilizer as the same time), mix even with ditch soil, transplant the seedling, casing into concave shape for collecting water, can water again if water is available.
