Explanation
WSF (Water Soluble Fertilizer) through a drip system results in more nutrient run-off compared to CRF (Controlled Release Fertilizer). This is because WSF is soluble in water and is immediately available for plants to uptake, while CRF releases nutrients slowly over time. When WSF is applied through a drip system, any excess nutrients that are not taken up by the plants can easily be washed away with water, leading to more nutrient run-off.

Explanation
Mum production can be challenging because they may be grown in economical growing media, which may not provide optimal conditions for growth. They are generally grown outside with poor environmental controls, which can lead to unpredictable weather conditions and pest infestations. Margins are slim in the mum production industry, so costs must be carefully managed to ensure profitability. Additionally, run-off can be an issue, as excess water and fertilizers used in mum production can contribute to environmental pollution. Therefore, all of the mentioned factors contribute to the challenges faced in mum production.

Explanation
WSF stands for Water-Soluble Fertilizer, which is typically more expensive to produce compared to CRF (Controlled Release Fertilizer). This is because WSF requires more processing and refining to make it water-soluble, allowing for immediate absorption by plants. On the other hand, CRF releases nutrients slowly over time, requiring less processing and therefore, lower production costs.

Explanation
Reducing WSF concentrations from 250 ppmN to 125 ppmN during week six to seven is necessary because it allows for a gradual decrease in the concentration of WSF over time. This gradual reduction helps to prevent any sudden changes in the nutrient levels, which could potentially harm the plants. By reducing the concentration during this specific time period, it ensures that the plants have received enough nutrients in the earlier stages of growth and are now ready to transition to a lower concentration without any negative effects.

Explanation
Drip irrigation systems are best for water-soluble fertilizer (WSF) application because they deliver the fertilizer directly to the plant roots, minimizing waste and ensuring efficient nutrient uptake. This targeted application reduces the risk of fertilizer runoff and leaching, which can lead to environmental pollution and loss of nutrients. Additionally, drip irrigation systems allow for precise control over the amount of fertilizer applied, helping to save costs by avoiding over-application. Therefore, using drip irrigation systems for WSF application is a practical and effective way to minimize fertilizer waste and save money.

Explanation
The correct answer is "All of the above" because Osmocote Plus is the best controlled-release fertilizer (CRF) for fall mum production for several reasons. Firstly, the product is 100% coated, which ensures that it is safe to use. Secondly, each prill of the fertilizer provides consistent nutrients, ensuring that the mums receive a balanced and adequate supply. Thirdly, Osmocote Plus utilizes Scott Patterned Nutrient Release technology, which releases the nutrients gradually over time, providing sustained feeding for the plants. Lastly, the fertilizer also contains magnesium and micronutrients, which are essential for the healthy growth of fall mums.

Explanation
The best CRF release pattern for fall mums is "Hi-start". This suggests that using a high-release pattern of controlled-release fertilizer (CRF) would be most beneficial for fall mums. This type of fertilizer slowly releases nutrients over time, providing a steady supply of essential elements to the plants, which is particularly important during the fall season when mums are actively growing and preparing for winter. Using a high-release pattern ensures that the plants receive an adequate amount of nutrients for optimal growth and development.

Explanation
The best rate to use on a 100% CRF, fall mum fertilization program is medium. This suggests that using a moderate amount of fertilizer is most effective for the program. Using a low rate may not provide enough nutrients for the mums, while using a high rate may lead to over-fertilization and potential damage to the plants. Therefore, a medium rate is recommended as it provides a balanced amount of nutrients for optimal growth and health of the mums.

Explanation
The statement suggests that the size of a fall mum plant can be controlled or altered by choosing different rates, longevities, and nutrient release patterns. This implies that by adjusting these factors, one can influence the growth and development of the plant, potentially resulting in larger or smaller sizes. Therefore, the statement is true.

Explanation
CRF stands for Continuous Reinforcement Fibers, while WSF stands for Woven Structural Fabrics. CRF is a type of reinforcement material that is continuous and evenly distributed throughout the entire structure, while WSF is a fabric made by weaving fibers together. The given statement suggests that using CRF in production can help reduce the time required for production compared to using WSF. This is because CRF can be easily integrated into the production process without the need for weaving, resulting in faster production times. Therefore, the answer "True" indicates that CRF is indeed capable of reducing production time compared to WSF.
