Section 3 • Living Soil, Integrated Soil Nutrient and Crop Managements<br />

5 List down all pertinent observations on farmers’ innovative soil and nutrient management<br />

practices.<br />

3. Present output <strong>of</strong> small groups to big group. Conduct participatory discussion to allow sharing<br />

<strong>of</strong> experiences among participants. Relate soil fertility assessment and STK analysis results to<br />

abundance <strong>of</strong> soil organisms, soil organic matter content, and soil water holding capacity, soil<br />

nutrient availability, and crop productivity.<br />

4. Synthesize and summarize output <strong>of</strong> small groups into one big group output. Draw up<br />

conclusions and recommendation from this exercise.<br />

some suggested questions <strong>for</strong> processing discussion<br />

❏ How many soil samples are required in a hectare <strong>of</strong> vegetable field? Did you see variations in<br />

color and textures in different soil layers?<br />

❏ Why is there a need <strong>for</strong> soil sampling? How <strong>of</strong>ten should a farmer subject his vegetable field<br />

to soil analysis?<br />

❏ What procedures are to be followed in taking soil samples from a vegetable field with different<br />

elevations?<br />

❏ What are the steps necessary be<strong>for</strong>e and after taking soil samples?<br />

❏ What are the different procedures in analyzing soils? What are their advantages and<br />

disadvantages?<br />

❏ Were the results <strong>of</strong> STK analyses con<strong>for</strong>m to expectations <strong>of</strong> farmers?<br />

❏ Were there differences in results between different soil samples analyzed?<br />

❏ What are the limitations <strong>of</strong> using STK <strong>for</strong> soil analysis?<br />
