WEEK 1 &2 – sample preparation for N, theory of elemental analyzer Week 3 & 4- BOE analysis, soil analysis (total phosphorus, available phosphorus and moisture content) Week 5- fertilizer analysis (digestion, moisture content, particle size) INTRODUCTION
fertilizer-substances that added to the soil or plant tissues. What is fertilizer?

Determination of moisture content
Percent by weight W1 is the weight in g of the sample taken. W2 is the weight in g of the sample after drying to constant weight. Sample ID = 327 Sample weight (g) = 10.000 Dish weight (g) = 29.470 Weight (dish + sample) after (g)= 39.076 W1 = 10.000 W2 = 9.606 EXAMPLE CALCULATION MOISTURE (%)
CONCLUSION ELEMENT FUNCTION N To assist the growth of trees. P Important in cell division and development of new tissue. K Required in large amounts for proper growth and reproduction of plants. Mg Building block of chlorophyll which makes leaves appear green. B Role in forming and strengthening cell walls.
