Proactive Approach to Soil Analysis

MEGALAB.net Full Spectrum Soil Analysis - The Proactive Approach

Historically the parameters analysed on a soil sample have been limited. N, P, K and pH are really the only standard tests done. This is now changing as the importance of the secondary (Magnesium, Calcium, Sulphur) and micronutrients (Boron, Copper, Manganese, Iron, Zinc and Molybdenum) is realized.

Make the most of your analysis

In order to make the most of the time and effort spent soil sampling the full spectrum of nutrients should always be analysed. By limiting the nutrients tested you run the risk of overlooking a key deficiency and losing out on yield and quality.

The table shows the deficiency levels of key nutrients in prairies soils from the 2001 season (1,000 + samples).

Key Products for Prairies Crops

Zintrac 700 contains 700 g/l zinc which is an important nutrient for the correct growth and development of dry beans. It plays a role in the functioning of many plant enzymes (catalysts) and also is necessary for plant hormone synthesis (auxins).

Coptrel 500 contains 500 g/l copper which is an important nutrient for photosynthesis, manufacture of lignin (cell walls) and of key importance for grain production in cereals. Deficiency can lead to poorly filled heads.

Sulphur F3000 contains 340 g/l sulphur which is important for protein development and therefore very important for many plant processes. Sulphur also has a key role in oil crops and is becoming more of an issue as pollution decreases.

Bortrac 150 contains 150 g/l boron which is also important in canola production due to its role in meristem growth and pollen germination. Low levels can affect flowering, pod set and pod fill.

The most effective analysis is the most proactive

The earlier in the season you analyze, the more time and options you have at your disposal. Soil analysis is the starting point from which to build your fertility program. The secondary and micronutrients must be included in the analysis to get the full picture.
