• Clay has fine, dense particles that do not allow

  water to soak in easily. Clay soils absorb water slowly, so it is best to water deeply and gently at long intervals. When clay soils are dry, they can become hard and resist water. However, when wet, they can hold moisture for a long time, which may not need watering again for a while.
• Clay soil

  • Fine, dense particles that do not allow water to soak in easily
  • Absorbs water slowly, best to water deeply and gently at long intervals
  • When dry, can become hard and resist water
  • When wet, can hold moisture for a long time
• Plants that grow in clay soil

  • Rice
  • Lettuce
  • Pechay
  • Mustard
  • Cabbage
  • Broccoli
  • Corn
  • Squash
• Ways to improve clay soil

  Add organic manure, tree bark, decayed leaves to improve structure, drainage and lessen stickiness
• Sandy soil

  • Feels gritty and drains easily
  • Dries out fast
  • Easier to cultivate
  • Warms up fast during summer
  • Holds fewer nutrients as they are often washed away
• Plants that grow in sandy soil

  • Carrots
  • Radishes
  • Pineapples
  • Potatoes
  • Tomatoes
  • Lettuce
  • Beans
  • Cucumber
  • Watermelons
• Ways to improve sandy soil

  • Add well-rotted manure or compost like fruit and vegetable peelings, dry leaves, and plant branches
  • Mix vermi compost to amend poor nutrient level
• Silty soil

  • Made up of rocks and mineral particles larger than clay but smaller than sand
  • Mostly found beside riverbanks where water current carries and deposits them
  • More fertile and good for growing crops

  
• Plants that grow in silty soil


  • Different plants, fruits, vegetables, trees, and shrubs
• Ways to improve silty soil


  Add composted organic matter to help improve drainage, add structure, and add nutrients
• Loam soil

  • Contains a balanced mixture of sand, silt, clay, and humus
  • Soft but gritty to touch, dry, and crushes easily to provide excellent draining properties
  • Retains water and plant nutrients which benefits plants with consistent moisture and food
  • Crumbly texture allows air to flow easily to the roots
• Ways to improve loam soil

  • Regularly replenish with organic matter to prevent nutrient depletion and drying out
  • Practice crop rotation and compost application to retain soil vitality
• Most plants can adapt, thrive and grow better on other types of soil like in clay, sand, and silt
• Importance of soil

  • Without soil, we cannot grow the food that we need to live
  • It is the backbone of our food security.
  • Fertile, healthy soil provides us feed, fiber, food, and fuel.
  • Soil is home for beneficial soil microbes
  • Soil is habitat for many other organisms
  • Used to make bricks, cement, adobes, pottery
  • Filters surface water of dust, chemicals, and other contaminants
  • Used in medicine, most antibiotics obtained from soil microbes
  • Helps regulate the Earth's temperature
  • Stores history from dinosaurs to ancient human civilization
