The role of temperature and humidity monitoring in agriculture

Temperature and humidity monitoring plays a vital role in agriculture, which is mainly reflected in the following aspects:

Real-time data monitoring and decision support

The temperature and humidity monitoring system collects temperature and humidity data in the soil in real time through high-precision sensors, and transmits these data to the central processing platform for analysis. These real-time data provide important decision-making support for farm managers, enabling them to understand the health of the soil in a timely manner and take corresponding management measures based on the data.

Improve work efficiency

By monitoring the temperature and humidity data of the soil in real time, farm managers can more accurately grasp the health of the soil and take timely measures to adjust it.

Precise irrigation management

The soil temperature and humidity monitoring system can provide precise irrigation suggestions based on soil moisture data. For example, when the soil moisture is lower than the set value, the system will recommend turning on the irrigation system and providing the appropriate amount of water. This precise irrigation management can avoid excessive or insufficient irrigation and improve the efficiency of water resource utilization.

Fertilization optimization

Soil temperature and humidity information can help optimize fertilization plans. Fertilizers are most effective under suitable temperature and humidity conditions. The system can recommend fertilization time and fertilizer type based on soil moisture and temperature changes to improve fertilizer absorption and utilization efficiency.

Crop variety selection

By analyzing soil temperature and humidity conditions, the system can recommend suitable crop varieties. For example, under drought or high temperature conditions, the system can recommend drought-resistant or high-temperature-resistant crop varieties to improve crop adaptability and yield.

Pest and disease warning

Soil temperature and humidity data combined with meteorological data can predict the occurrence of pests and diseases. For example, excessive humidity may cause fungal diseases, while abnormal temperature may cause pests to breed. The system can provide pest and disease warnings to help farmers take timely prevention and control measures.

Growth monitoring and adjustment

Real-time monitoring of soil environmental conditions can help track crop growth. If it is found that temperature and humidity conditions are not conducive to crop growth, the system can recommend adjustments to planting strategies or management measures, such as adjusting irrigation frequency, changing fertilizer ratios, etc.

Promoting the development of intelligent agriculture

The application of soil temperature and humidity monitoring systems has promoted the development of intelligent agriculture. By integrating technologies such as the Internet of Things, big data, and artificial intelligence, the system can achieve comprehensive monitoring and intelligent analysis of the farmland environment, providing farmers with more convenient and efficient farmland management solutions.

Ammonia Hazards on Breeding Farms

Ammonia gas is a poisonous substance for living organisms. Especially the brain tissue of higher animals is extremely sensitive to ammonia, and the concentration of ammonia in the blood reaches 1%, which can cause central nervous system poisoning. Ammonia is harmful to the organism, mainly irritating the mucous membranes of eyes and respiratory system, increasing the susceptibility to respiratory diseases, and affecting the feed intake, food conversion efficiency and growth rate.

1. Induce Respiratory Diseases

Ammonia is a kind of alkaline substance, which has a strong corrosive and irritating effect on the mucous membranes of skin tissues in contact with it. Ammonia's solubility is very high, very easy to dissolve in water, it absorbs the water on the surface of the skin tissue, makes the tissue protein denaturation and saponification of the tissue fat, destroying the cell membrane structure. Ammonia in the chicken house mainly has a corrosive and irritating effect on the upper respiratory tract of animals. High concentrations of ammonia can stimulate the upper respiratory tract tender epithelial tissue, so that the pharynx and trachea epithelial tissue cells edema, degeneration, or even necrosis, accompanied by the loss of cilia, mucus secretion of cells increased, respiratory dysfunction and a series of pathological changes.

2. Induce Broiler Ascites Syndrome

The current unified view is that broiler ascites is caused by chronic hypoxia. Excessive concentration of ammonia in the environment will stimulate the mucous membrane of the upper respiratory tract, making it congested, edematous and increasing secretions. After it is inhaled into the lungs, it can freely pass through the alveolar epithelium into the bloodstream, increasing the blood ammonia concentration. Ammonia combines with hemoglobin to reduce the oxygen-carrying capacity of hemoglobin, leading to oxygen deficiency, which will also cause broiler ascites syndrome.

3. Inducing Eye Diseases

Ammonia dissolves in eye secretions and produces ammonium hydroxide, which induces keratoconjunctivitis, adhesion of the eyelids and clouding of the cornea. When the concentration of ammonia gas is persistently higher than 100 ppm, it will trigger corneal ulcers and blindness. Tear spots are common, and the formation of tear spots firstly affects the growth rate of pigs, and secondly causes a decline in the immunity of pigs, which is a sign of infection with infectious diseases.

4. Affecting the Chicken's production performance

When the concentration of ammonia in the chicken house is too high, the chickens are characterized by lack of spirit, reduced activity, reduced feed intake, growth rate and egg production rate are significantly reduced. Ammonia in the coop comes from the nitrogenous organic matter in the excreta, and a large amount of protein in the ration cannot be fully utilized by the body, resulting in a reduction in the feed conversion rate of chickens. Studies have shown that when the ammonia concentration reaches 50-75ppm, the feed intake and feed conversion rate of chickens can be reduced.

5. Affecting the Immune Effects of Vaccines

Many of the vaccines that are immunized by eye-dotting, nose-dropping and spraying are first invaded into the respiratory epithelial cells, then replicated and proliferated in them, stimulating the body to produce a series of immune responses. The ammonia concentration in the chicken house is too high, the ammonia will damage the respiratory epithelial cells, so that the vaccine is difficult to give full play to its role, which in turn causes the immunization effect of the chickens to reduce or no immunization effect.

Respiratory Problems: PM2.5 can cause or exacerbate respiratory diseases such as asthma, bronchitis, and other chronic obstructive pulmonary diseases (COPD). 2. Cardiovascular Issues: Long-term exposure to PM2.5 can lead to cardiovascular problems like heart attacks, strokes, and even premature death in people with heart or lung disease. 3. Allergic Reactions: PM2.5 particles can trigger allergic reactions and irritations in the eyes, nose, and throat. 4. Impaired Lung Development: In children, prolonged exposure to PM2.5 can lead to impaired lung development and reduced lung function. PM2.5 doesn't just affect human health; it also has detrimental effects on the environment. These include: 1. Visibility Impairment: High concentrations of PM2.5 can reduce visibility, leading to hazardous driving conditions and affecting the aesthetics of landscapes. 2. Acid Rain: The chemical reactions that form PM2.5 can also lead to the production of acidic particles, contributing to the phenomenon known as acid rain. Acid rain can harm forests, acidify water bodies, and damage buildings and monuments. 3. Climate Change: Some components of PM2.5 can affect the planet's climate. Black carbon, a significant component of PM2.5, can absorb sunlight and contribute to global warming. Reducing the levels of PM2.5 requires concerted efforts at individual, community, and governmental levels. Some measures include: 1. Regulatory Standards: Governments should set and enforce stringent air quality standards to regulate the emissions of PM2.5 and its precursor gases. 2. Clean Energy Transition: Shifting from fossil fuels to renewable sources of energy can significantly reduce the emissions contributing to PM2.5 formation. 3. Public Awareness: Raising public awareness about the health and environmental hazards of PM2.5 can encourage individual actions to reduce personal exposure and emissions. 4. Technological Innovations: Development and adoption of technologies that reduce or capture PM2.5 emissions can be instrumental in combating this issue. The formation and hazards of PM2.5 present a significant global challenge. Given its severe impacts on human health and the environment, comprehensive strategies are needed to control the sources of PM2.5 and mitigate its effects. From adopting clean energy sources and implementing regulatory standards to increasing public awareness and fostering technological innovations, every effort counts in the battle against PM2.5.
