Across
- 1. - Promotes leaf and stem growth, aids in carbohydrate metabolism, and helps in the formation of chlorophyll.
- 6. : Fertilizers manufactured through chemical processes, typically containing concentrated forms of nitrogen, phosphorus, and potassium. Inorganic fertilizers provide nutrients to plants quickly but may lead to nutrient runoff and soil degradation if used excessively.
- 9. - Plays a crucial role in chlorophyll synthesis, promotes root growth, and enhances plant defense mechanisms.
- 13. - Stimulates root development, promotes flower and fruit formation, and aids in early plant growth.
- 16. : Nutrients required by plants in smaller quantities but are equally essential for their growth and development. Micronutrients include iron, zinc, copper, manganese, boron, molybdenum, and chlorine.
- 18. : Fertilizers derived from natural sources such as compost, manure, bone meal, or blood meal. These fertilizers release nutrients slowly as they decompose, improving soil structure and fertility over time.
- 19. : Any substance or mixture of substances added to soil or plants to supply one or more essential nutrients that are deficient in the soil or plant. Fertilizers can be organic (derived from living organisms or natural sources) or inorganic (synthetically manufactured).
Down
- 2. : Substances essential for plant growth, which can be obtained from the soil or through fertilizers. These include macronutrients (required in large quantities) such as nitrogen, phosphorus, and potassium, as well as micronutrients (required in smaller quantities) such as iron, zinc, and manganese.
- 3. : Nutrients required by plants in relatively large quantities for optimal growth and development. In addition to nitrogen, phosphorus, and potassium, macronutrients also include calcium, magnesium, and sulfur.
- 4. - Prevents disorders such as blossom end rot in tomatoes and maintains cell membrane integrity.
- 5. - Prevents chlorosis (yellowing of leaves) and promotes green coloration in plants.
- 7. : Facilitates electron transfer reactions, promotes overall plant metabolism, and helps in the formation of lignin.
- 8. - Enhances disease resistance, improves drought tolerance, and contributes to overall plant health and vigor.
- 10. : Any substance added to soil to improve its physical or chemical properties, such as fertility, structure, or pH. Amendments can include both fertilizers and organic materials like compost or peat moss.
- 11. - Essential for the formation of chlorophyll, necessary for the production of essential oils and flavor compounds in certain plants.
- 12. - Essential for photosynthesis, aids in the formation of sugars and starches, and promotes overall plant growth.
- 13. A measure of the acidity or alkalinity of soil, which affects the availability of nutrients to plants. Soil pH is important for nutrient uptake and overall plant health, with most plants preferring a slightly acidic to neutral pH range (around 6.0 to 7.5).
- 14. - Promotes leafy green growth, improves overall plant vigor, and enhances photosynthesis.
- 15. Fertilizers designed to release nutrients gradually over an extended period, providing a consistent supply of nutrients to plants while reducing the risk of nutrient leaching and runoff.
- 17. : An abbreviation for nitrogen (N), phosphorus (P), and potassium (K), which are the three primary macronutrients essential for plant growth. NPK fertilizers are formulated to provide these nutrients in specific ratios to meet the needs of different plants at different growth stages.
