Causes of Moss Growth on Greenhouse Soil and Solutions

If you are observant, you may notice that soil in areas with high humidity usually grows moss, and this also happens from time to time in some farmers' agricultural greenhouses. So exactly why does soil grow moss? What should be done about moss growing inside a greenhouse?

Causes of moss growth on soil

1. High soil moisture and dampness

Moss is a bryophyte, suited to growing in water or in shady, damp places by the sea, and it grows year-round in wetlands, on walls, in wells, on roof tiles and in water. This is also why moss grows easily after flood irrigation or rain; heavy downpours can easily cause backflow, and combined with continuous rainy weather, this leads to runaway moss growth.

2. Eutrophication (the deterioration of water quality caused by excessive nutrients)

We all know that when water contains excessive amounts of nutrients such as nitrogen and phosphorus, eutrophication of the water body occurs and algae and other plankton multiply in large numbers. If the nutrient content in the soil is relatively high, similar symptoms can also form, and moss growth is one of the causes.

3. Soil quality problems

Soil that is too acidic, too alkaline or severely compacted: when the soil pH is too low or too high, the plant root system is adversely affected, so nutrients cannot be taken up, and when nutrients in the soil are excessive, moss growth occurs.

What should be done about moss growing inside a greenhouse?

1. Pay more attention to soil moisture, and especially after rainwater backflows into the greenhouse, drain the water as soon as possible.

2. Choose appropriate fertilizers to apply, especially phosphate fertilizer, and be careful to keep soil nutrients balanced.

3. Improve soil quality, especially by maintaining the soil's acidity and alkalinity and its air permeability, and apply more high-quality organic fertilizer and soil conditioners to finely adjust soil quality. On the one hand, this can activate the various nutrients in the soil and improve nutrient use efficiency; on the other hand, it can promote the development of the plant root system and its uptake of nutrients.

4. Ventilate and remove moisture in time to reduce the humidity on the soil surface, which can reduce the occurrence of moss.
