A unique approach to the treatment of nutrient excesses and deficiencies

THE ANALYTICAL APPROACH TO SOLVING PROBLEMS CAUSED BY NUTRITIONAL EXCESSES AND DEFICIENCIES

Nutrient deficiencies and excesses can seriously reduce both crop quality and yields while increasing the susceptibility to disease and pest attack. Precise identification of problem areas allows preventative action to be taken by means of a carefully planned crop nutrition programme.

Tissue analysis should be used to carry out a spot check on nutrient status and soil analysis to determine the relative levels of all the essential elements.

Analysis of spray tank water supply and irrigation water can identify factors leading to detrimental pesticide hydrolysis or application of unwanted elements.

Nutrient solution analysis can help to ensure the correct fertiliser balance in NFT/Rockwool enterprises.

A computerised interpretation of the analytical results provided by a wholly independent laboratory, backed-up by the services of an experienced agronomist, enables the farmer to determine the best treatment to solve the problem.

Often the deficiency of an essential element does not occur alone, other nutrients may be deficient or in excess. The application of only one nutrient may increase growth rate and cause a nutrient, which is borderline, to become deficient. Therefore, the status of all the nutrients should be monitored together so that application of one element does not reduce the availability of another.

ANALYSES AVAILABLE:

TISSUE: N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, Zn.

SOIL: P, K, Ca, Mg, S, B, Cu, Fe, Mn, Mo, Zn, pH, Lime required, OM.

IRRIGATION WATER AND NFT/ROCKWOOL SOLUTIONS: NH4-N, NO3-N, P, K, Ca, Mg,
Na, SO4-S, B, Cl, Cu, Fe, Mn, Zn, HCO3, Conductivity.

SAP NITRATE: NO3-N using Merk strips and Nitracheck reflectometer.

All Nu-Trel Analytical Service soil reports are held in computer records for four years, after which customers are advised that the field should be re-analysed. If fields are not limed or subject to excessive applications of manure, soil levels do not fluctuate wildly, so for the 3 years following the original analysis, each year we can advise what crop treatments are suitable if the customer tells us what crop he intends to grow.
