YaraTera NITRAKAL provides a balanced formulation of nitrogen, potassium and calcium that are immediately available for tomato plants. Nitrogen and potassium are fundamental to achieving high marketable yields. Potassium is also the main nutrient affecting the quality of the tomato, improving the uniformity of ripening, acidity and taste of the fruit. Maintaining high potassium and nitrogen levels in the fruit will minimize blotchiness and greenback problems in fruit. Good calcium nutrition is also essential for ensuring good quality tomatoes.
YaraTera NITRAKAL works as a part of all fertigation systems and management practices by providing immediately available key nutrients at critical stages that have a fundamental role in ensuring a higher yield and better tomato quality.
These tomatoes represent the crop harvested from the two 20-acre research blocks that were grown using the growers' standard practice and the Yara PrimeTomatoes Solution. The two blocks were managed the same except for the nutrition program. The Primetomatoes Solution including YaraTera NITRAKAL resulted in an ROI of $470/acre.
In field trials in the Northern Central Valley of California, YaraTera NITRAKAL increased total income compared to untreated and gave an increased net return of $ $367/ac or 3.1 to 1. For every $1 invested into the YaraTera NITRAKAL combined program, 3.1 additional dollars were generated.
In this trial, a late-season application of YaraTera NITRAKAL increased total income compared to untreated and gave a net profit of $182/ac. Returns have increased 5.2 times for every additional dollar invested in the program that included YaraTera NITRAKAL.
Nitrogen and potassium are fundamental to achieving high marketable yields. Take a look at these tomato trials where the Yara programs including YaraTera NITRAKAL have resulted in significant yield increases.
Field trials conducted in 2019 showed a 7 ton/ac yield increase when YaraTera NITRAKAL was tested against a baseline program. The YaraTera NITRAKAL combined program included the replacement of three applications of UAN-32 / CAN-17 / KTS during fruit development stages by applications of YaraTera NITRAKAL.
The late YaraTera NITRAKAL application trial followed a baseline program with the only difference of only one application of YaraTera NITRAKAL at 20 gal/ac during fruit sizing stages. The treated block of 38 acres showed an increased marketable yield compared to the untreated of 9%.
Nitrogen and potassium are critical for ripening uniformity, color and proper brix in tomatoes. Calcium is vital for improving crop quality, health, and growth, and it is key to good soil quality. In this tomato trial, the Yara program including YaraTera NITRAKAL resulted in higher brix and less fruit defects.
Successful tomato production requires both high yield and good fruit quality. Uneven ripening of tomato fruit is a classic symptom of potassium deficiency. Plants that received balanced applications of nitrate-nitrogen, soluble calcium and potassium in YaraTera NITRAKAL show improved color, ripening uniformity and less defects, such as, blossom end rot.
Root health is dependent on proper crop nutrition and without a healthy root system tomato plants won’t thrive. The trials conducted in California show that by using a balanced crop nutrition approach with YaraTera NITRAKAL tomato plants were healthier with larger root growth and density.

Plant growth and fruit development were measured during the season on both the baseline and the YaraTera Nitrakal programs. Plants treated with YaraTera NITRAKAL show better root structure, increased vigor and improved crop potential.
Nitrate-nitrogen in YaraTera NITRAKAL promotes uptake of critical nutrients in high demand at this stage such as calcium and potassium. A balanced nitrate-N, K and Ca formulation will minimize heat stress and blossom drop, increasing yields.
The highest demand for potassium occurs during tomato bulking. Maintaining a balanced N/K ratio in fertigation solution will minimize fruit quality problems, improve the levels of sugar in the fruit, and promote more uniform ripening. Calcium nutrition will minimize the occurrence of blossoms end rot, increasing quality and marketable yields.
Yara is committed to helping farmers grow PrimeTomatoes in terms of yield and quality, having an impact on their profitability. Crop knowledge, application competence-including technology tools and services- and the most comprehensive crop nutrition portfolio on the market make up the core of Yara’s Crop Nutrition Solution for tomatoes.
