Features Application & effectiveness Application Tips and Dosage SAP Application Guidelines

SAP Application Guidelines in Crops & Plants

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.

Application method as belows:

A : Basal application

  • Use dry method for moistly soil: mix SAP with 10 to 30 times dry fine soil then apply into the planting trench;
  • 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.
  • If in mechanical sowing, mix SAP with soil, thrown into the terraces with base fertilizer, watering immediately after sowing.

16 For all kinds of fruit trees

Such as citrus, apple, pear, peach, jujube, walnut, chestnut, banana, waxberry, lychee, mango etc.

A: For adult trees:
50~100g/tree, application method: bar facilities or hole application.

Application time:

  • Use dry method 5~10days earlier before the rainy season (absorb water in rainy season, release water in drought time).
  • Mix SAP with fertilizer in winter before or after picking the fruit or use wet method in spring fertilization.
  • Mix SAP with fertilizer 20days earlier before flowering, can use wet method.

Application method:

  • Dig a long trench with depth more than 20cm from on side of the fruit trees drip line (can see the fibrous root), or dig 2 ~ 5 hole around the drip line (can see the fibrous root), use dry method before rainy season or with water available: put SAP directly into the hole, fertilizer can be put at the same time, mix even with hole soil, casing into a concave shape for collecting water, watering immediately.
  • In drought time, winter or spring time, wet method is suggested, make SAP into 200 times hydrogel and apply into the ditch or hole ( fertilizer can be put at the same time), mix even with soil, casing into concave shape for collecting water, watering again if water is available.

B: For young trees:
10~40g/tree, application method: bar facilities or hole application.

Application time:

  • 5~10days earlier before the rainy season
  • Mix SAP with fertilizer in winter before or after picking the fruit or use wet method in spring fertilization.
  • In winter or spring fertilization time, the application method is the same as per the adult trees.

1: For fruit trees transplant:
10~50g/ tree

Application method:

For dipping: Seedings might loss moisture during long-distance transport. The Soiled mud or put a layer of greenhouse straws on the surface of film, and keep watering during transport, which are the inconvenient traditional transport. For the sake of transport convenience, we developed a replacement product: dipping agent, product type:DP300, it's potassium based SAP combined with a special binder, which can form a thin film and be attached in the root of seedlings after hydrated.

Using method: make SAP into a certain concentration water gel, mix evenly around 30minutes, dip the seedlings for 30 seconds then take out, dripping is appropriate, the gel will be attached on the root of seedlings, add some mud and wrapped with plastic sheeting before transport, the effect will be better. Normally the concentration is 0.1%, and 1kg dipping agent can be used min. for 2000 seedlings

Basal application: it's the same as per the wet or dry method of adult trees, better use wet method. Attn: no matter for dipping or basal application, shall be used in conjunction with each other, wet method in basal application is no need for dipping. If the transplant is not done in rainy season, watering is a must after planting, and casing into concave shape for collecting water.

ii: For cutting:
10~50g/ tree

According to the dosage of 5 ~15g dry powder/M2 on the seed bed, basal application when making it to 100times hydrogel, leveling the seed bed and cover a thin layer of soil, root the cuttings dipped with dipping agent
