Exploring Organic and Smart Agriculture

What is compost manure and its role in organic crop production?

• Compost manure is fresh animal waste that should be applied directly to crops.

• Compost manure is decomposed organic matter used as fertilizer in organic crop production.

• Compost manure is a type of pesticide for crop protection.

• Compost manure is synthetic fertilizer used in conventional farming.

How can the quality of water affect organic farming?

• Poor water quality can enhance soil fertility.

• Water quality has no impact on pest control methods.

• Organic farming does not require any water for crop growth.

• Water quality is crucial for soil health, crop growth, and pest management in organic farming.

List some organic fertilizers and their benefits.

• Herbicides: Kill weeds but do not enhance nutrient content.

• 1. Compost: Improves soil structure and provides a balanced nutrient supply. 2. Manure: Adds organic matter and nutrients, enhancing soil fertility. 3. Bone Meal: Rich in phosphorus, promotes root development and flowering. 4. Fish Emulsion: Provides nitrogen and trace minerals, boosting plant growth.

• Pesticides: Control pests but do not contribute to soil fertility.

• Synthetic fertilizers: Provide quick nutrient release but can harm soil health.

What are organic pesticides and how do they differ from synthetic ones?

• Synthetic pesticides are derived from plants and minerals.

• Organic pesticides are always more effective than synthetic ones.

• Organic pesticides are only used in gardening and not in agriculture.

• Organic pesticides are natural substances used to control pests, while synthetic pesticides are chemically manufactured substances.

Explain the use of parasitoids in pest control within organic farming.

• Parasitoids are harmful insects that increase pest populations.

• Parasitoids are primarily used for soil fertilization in organic farming.

• Parasitoids are used in organic farming as biological control agents to manage pest populations sustainably.

• Parasitoids are synthetic chemicals used in conventional farming.

What steps are involved in conducting an on-farm trial for organic crops?

• The steps involved in conducting an on-farm trial for organic crops include defining objectives, selecting site and crops, random assignment of treatments, implementation, data collection, analysis, and reporting.

• Conducting trials without a defined objective

• Selecting only one crop variety

• Ignoring data collection

Identify some organic materials that can be used in crop production.

• Synthetic fertilizers

• Pesticides

• Compost, manure, cover crops, green manure

• Herbicides

What are the advantages of hydroponics over traditional soil farming?

• Higher nutrient levels in soil

• Increased labor costs

• Advantages of hydroponics include efficient water use, faster growth, reduced disease risk, and suitability for poor soil areas.

• Longer crop cycles

Discuss the disadvantages of using hydroponics for crop production.

• Lower water usage compared to traditional farming

• Disadvantages of hydroponics include high initial costs, dependence on electricity, susceptibility to diseases, labor-intensive nutrient management, and limited crop diversity.

• Higher crop yields with less effort

• Greater variety of crops available for all climates

What are the different types of growing media used in hydroponics?

• Soil mix

• Sand

• Peat moss

• Rock wool, coconut coir, perlite, vermiculite, clay pellets
