Crop Sizing

Introduction

Developing quality of fruit is important in today’s agriculture market. While there are many quality indicators that affect a grower’s ROI, crop sizing will directly impact the bottom line. Nutrient management and balanced plant nutrition will directly impact crop sizing. Three important nutritional factors to discuss are nitrogen metabolism, potassium nutrition and bio-active carbon compounds.

Key Facts

Nitrogen Metabolism

Nitrate-nitrogen is extremely mobile in the soil and easily absorbed by the root membrane and stored in the leaf cell vacuole. Nitrate-nitrogen stored in leaf cells is of minimal value. Excess accumulation of nitrate-nitrogen in the cells leads to chemical and physiological changes in the cells that are detrimental. Some of these affects are weaker cell walls (leads to abiotic and biotic stresses), increased vegetative growth, and reduced reproductive crop potential.

The process of converting nitrate-nitrogen into amino acids is called nitrogen metabolism. In order for nitrogen metabolism to occur, the plant needs soluble carbohydrates to convert the nitrogen into amino acids. The soluble carbohydrates can come from stored reserves from previous year applications, but more times than not, the plant will need additional help to convert nitrogen into amino acids. These amino acids are the building block to the plant and lead to better reproductive growth and crop sizing.

Redox Solution

Supreme Flowable

A key technology for strategic nitrogen metabolism helping the plant convert nitrogen into amino acids is Supreme. Supreme is a reacted plant nutrient that contains soluble carbon compounds that are derived from a proprietary fermentation process. The combination of the plant available nutrients and specific soluble carbon from the fermentation process allow the crop to properly metabolize nitrogen. Supreme consistently promotes crop sizing under all conditions. Improved crop sizing can be a key strategy for improving yield.

Potassium Nutrition and Bio-Active Carbon Compounds

Carbohydrates are the basic energy source for plant function. Plants take in carbon dioxide and give up oxygen via the leaf stomata -this is respiration. Leaf temperature is a key abiotic stress factor which affects leaf stomata and the respiration process. Key potassium inputs that enable the plant to more efficiently respire help the plant combat high and low temperatures. More efficient daily respiration effectively enables allocation of carbohydrates and starches into developing nuts for improved nut fill and quality.

diKaP™

diKaP is formulated to provide efficient potassium nutrition. diKaP is specifically formulated to contain bio-active carbon compounds that improve antioxidant production and increase plant respiration. Efficient potassium nutrition and bio-active carbon compounds will help the plant respire and handle different abiotic factors.

Mainstay Si

A reacted nutrient product high in calcium and silicon with Redox microencapsulation technology for high uptake and movement within the plant.

Use in split applications of 1-2 quarts per acre on permanent crops applied at the latter stage of bloom and repeated 10-14 days later via foliar or fertigation application.

On annual crops apply 1 to 2 pints to 1 quart per acre during peak bloom or crop set and repeat in 7-14 days via foliar or fertigation application.

Other Factors to Consider

Calcium Nutrition

During early season cell development, calcium is allocated to cells and is irreplaceable for cell structure and strength. Strong cells correlate to higher crop performance potential. This cell development starts at the latter stages of bloom, new tissue development, and root expansion. Ninety percent of crop cell calcium uptake occurs during early season of deciduous tree and vine crops, and even faster in annual determinant crops. Non-determinant crops will go through this process as long as crop set, or harvestable crop development occurs.
