Question

Calcium formate with boron (B) and zinc (Zn)

Declared content (%w/w):

34% Water-soluble Calcium Oxide (CaO)
56% Formate
1% Water-soluble Boron (B)
2% Water-soluble Zinc (Zn)
2% Chelated Zinc (Zn) by EDTA
pH range for which a acceptable stability of the chelated fraction is guaranteed: 4-9

Fertilizer rich in calcium in the form of soluble powder, indicated to avoid fruit cracking, apical rot, bitter pit and improve its quality, firmness, consistency and post-harvest life. In addition to providing totally soluble and assimilable calcium, it provides formate ion, which contributes to its solubility, to the regulation of the pH of the solution and its conservation. It also includes boron and zinc as a complement to the plant's nutrition.

Appearance = White powder

pH (10% solution) = 6.5-7.5

The number of applications varies significantly depending on the crop. It is recommended to follow a technical criterion based on soil and foliar analysis, as well as having specific knowledge of the crop. The doses to be used per application are shown in the following table:

	Fertigation	Moment
Horticultural	5-10 kg/ha	4-8 treatments, flowering until color change
Horticultural green leaf	4-8 kg/ha	2-4 treatments per crop cycle
Citrus, fruit trees and vine	4-8 kg/ha	2-6 applications, from winter release to fruit set
Strawberry and berries	5-10 kg/ha	3-5 treatments, after the appearance of the first flowers

The amount of water used directly affects the effectiveness of the product: use a minimum of 500 l / ha.

In case of hydroponic crops, prepare a concentration mother solution between 6-10% (according to water quality).

A generic foliar dose of 200-450 g / hl can be established; the timing and the number of applications must be decided according to agronomic criteria.

Note: These recommendations are general and indicative, and must be adapted by a qualified technician based on agronomic and edaphoclimatic factors.
