Project Description
Product Description
Setra rock helps crops sensitive to nitrogen fertilization by adding calcium in the form of hydroxide without nitrogen during flowering for some crops and during the season for more sensitive crops.
Setra rock when added to the soil
– For vegetable crops sensitive to nitrogen – Helps to stabilize the knot and prevent fruit from falling. For fruit crops such as pear – apple – mango. – For crops sensitive to nitrogen fertilization, it helps to stabilize the knots and prevent the fruits from falling off. The compound works on the presence of calcium in a free form for the longest possible period and not losing it with repeated irrigation. It works to surround the root hairs with calcium, which facilitates their absorption.
For grapes:
Straw rock is added during flowering to most varieties of grapes, and for dense varieties of vegetative growth and colored varieties, specifically black ones, calcium is added from blooming until harvest in the form of straw “calcium oxide”.
It is used with all crops in general, but its effect on interim crops, and their life cycle is distributed in stages:
| Average per acre | Life Stage of plant | The crop | |
|---|---|---|---|
| 2k per acre | From a week before flowering until the beginning
Freshness of the kernels These are nitrogen sensitive varieties Calcium use all in one form calcium oxide |
grapes Specifically colored items Especially the black one | |
| Approximately 2 kg / acre in the treatment | Setra rock is used at the beginning of blooming Until harvest to avoid fire blight |
|
|
| 2k per treatment | During the flowering stage
From the beginning of flowering until the decade |
