Non-humic substances in humus are organic compounds that are not classified as humic substances. These can include proteins, amino acids, sugars, and other organic molecules that are partially decomposed plant and animal material. Non-humic substances play a role in nutrient cycling and soil fertility, contributing to the overall organic matter content of the soil. **

Humic substances are not necessary for betta fish, but they can provide some benefits. Humic substances can help create a more natural environment for bettas by mimicking their natural habitat and providing a source of beneficial bacteria. They can also help to lower the pH of the water, which may be beneficial for bettas that prefer slightly acidic water. However, it's important to use humic substances in moderation and to monitor water parameters to ensure they do not negatively impact the overall water quality. **

Humic substances or similar substances can be introduced into the aquarium in several ways. One common method is to use commercially available products such as peat moss, which can be placed in a filter bag or directly into the aquarium to release humic substances over time. Another method is to use natural materials such as driftwood or leaves, which release humic substances as they break down in the water. Additionally, there are liquid additives specifically designed to introduce humic substances into the aquarium. It's important to monitor water parameters and the behavior of the aquarium inhabitants when introducing these substances to ensure they are not adversely affecting the ecosystem. **

The choice between living in the countryside or in a village depends on personal preferences and lifestyle. Living in the countryside offers a peaceful and serene environment with more space and nature, while village life may provide a sense of community and convenience with amenities nearby. Both options have their own charm and appeal, so it ultimately comes down to individual priorities and what kind of lifestyle one desires. **

When visiting a village in the countryside, it's best to wear comfortable and practical clothing suitable for outdoor activities. This could include jeans, sturdy shoes or boots, and layers to accommodate changing weather. It's also important to be respectful of local customs and traditions, so consider wearing modest and conservative clothing. Additionally, it's a good idea to bring a hat, sunglasses, and sunscreen for sun protection, as well as insect repellent for outdoor activities. **

It is difficult to make a generalization about the friendliness of girls in rural villages versus cities as friendliness can vary greatly among individuals regardless of their location. However, some may argue that girls in rural villages might be perceived as friendlier due to the close-knit community and slower pace of life, which can foster stronger relationships and a more welcoming atmosphere. On the other hand, girls in the city may be more accustomed to a diverse and fast-paced environment, which could also lead to friendly interactions. Ultimately, friendliness is a personal trait that can be found in individuals regardless of where they live. **
