Q: How do you glue a broken plastic basin?: Find you a soft plastic, burn it, drop the drop of plastic in the dew place!!

Q: Are olive nets compatible with mechanical olive harvesters?: Yes, olive nets are compatible with mechanical olive harvesters. These nets are used to collect the olives that are mechanically shaken from the tree branches during the harvesting process. The nets are spread beneath the trees, allowing the olives to fall onto the nets, making it easier to collect and transport them efficiently.

Q: How do olive nets affect the overall oil content of the olives?: Olive nets have a minimal impact on the overall oil content of the olives. These nets are primarily used to prevent the olives from falling to the ground and getting damaged, rather than directly affecting their oil content. The oil content of olives is mainly influenced by factors such as olive variety, ripeness, and growing conditions, rather than the use of nets.

Q: Can olive nets be used on olive trees grown in cold climates?: Yes, olive nets can be used on olive trees grown in cold climates. Olive nets are commonly used to protect olive trees from extreme weather conditions, including frost and wind. By covering the trees with nets, the cold air is trapped, creating a microclimate that helps to maintain warmer temperatures around the trees. This can be particularly beneficial for olive trees grown in cold climates, as it helps to prevent frost damage and promotes healthy growth.

Q: Can olive nets be used for olive tree nutrient management?: No, olive nets are primarily used for harvesting olives and protecting them from birds, rather than for nutrient management of olive trees. Nutrient management involves the application of fertilizers and other practices to ensure optimal nutrient levels for tree growth and fruit production.

Q: Can olive nets be used for other crops?: Yes, olive nets can be used for other crops. Olive nets are commonly used for olives to protect them from birds and other pests, but they can also be used for other fruit trees and crops such as cherries, plums, and even vineyards to prevent damage and loss from birds and other animals.

Q: Can olive nets be used to protect against frost damage?: Yes, olive nets can be used to protect against frost damage. These nets are commonly used in olive groves to shield the trees from frost during cold weather conditions. The nets act as a barrier, preventing direct contact between the frost and the olive trees, thus reducing the risk of frost damage.

Q: Can olive nets be used in regions with limited labor availability for hand harvesting?: Yes, olive nets can be used effectively in regions with limited labor availability for hand harvesting. Olive nets are designed to catch the olives as they fall from the tree during mechanical harvesting methods. This eliminates the need for extensive manual labor and makes the harvesting process more efficient. Additionally, the use of olive nets can help reduce the dependency on human labor, making it viable even in regions with limited workforce availability.

Q: Can olive nets be used for olive trees in polluted environments?: Yes, olive nets can be used for olive trees in polluted environments. These nets serve as a protective barrier against various pollutants, including air pollution, dust, and debris. They prevent the accumulation of harmful particles on the leaves and fruits of olive trees, thereby helping to maintain their health and productivity. Additionally, the nets also offer protection against excessive sunlight, wind, and pests.

Q: Can olive nets be used on olive trees in pots or containers?: Yes, olive nets can be used on olive trees in pots or containers. The nets help protect the olives from birds and other animals while allowing air circulation and sunlight to reach the tree.
