Calcium Boron Foliar Spray for Crop Growth

Calcium boron spray is used to supply crops with two important nutrients through the leaves. Calcium supports cell wall strength, crop firmness, and overall plant structure, while boron supports flowering, pollen movement, fruit setting, and new growth. As a foliar spray, it is especially useful during growth stages when quick nutrient availability is needed.

Boron foliar spray helps support flowering, pollination, fruit development, and movement of sugars within the plant. Because it is applied directly to foliage, plants can absorb it quickly when conditions limit soil uptake. In a balanced calcium boron program, boron also complements calcium’s role in crop strength and reproductive growth.

Leher applies foliar nutrients using agricultural drones operated by trained pilots. Farmers book the service through the Leher App, after which a pilot arrives at the farm, completes the spray, and records the spraying history. Drone application provides uniform aerial coverage, reduces labor exposure, and can significantly lower water use.

Calcium boron foliar spraying can support many field, horticulture, and plantation crops when applied at the right stage. Leher’s drone spraying services are suitable for crops such as paddy, cotton, wheat, sugarcane, vegetables, tea, and plantation crops, with spray planning adjusted to canopy structure, crop height, and field conditions.

Calcium boron is commonly applied during active vegetative growth, pre-flowering, flowering, fruit setting, or early fruit development, depending on the crop. The exact timing should follow crop stage, nutrient deficiency signs, agronomist guidance, and product label directions. Drone spraying helps cover large fields quickly during these critical windows.

Drone foliar spraying offers faster coverage, more uniform application, and reduced direct chemical exposure for workers compared with manual spraying. Leher’s drone services can cover up to 50 acres per day and save up to 90% water. It is especially useful for tall, dense, wet, or difficult-to-access crop fields.

Farmers can book drone spraying through the Leher App, which handles scheduling, service coordination, secure payment after the job, and spraying-history records. Once booked, a trained drone pilot is dispatched to the farm. The process is designed to make professional foliar nutrient application accessible and convenient for farmers.

Calcium boron foliar spray is best used as a targeted nutrient support method, not a full replacement for soil fertility management. It helps provide faster nutrient availability through leaves during key crop stages. Farmers should still maintain balanced soil nutrition, irrigation, and crop-specific fertilizer plans for sustained growth and productivity.
