Is 50dB a Safe Noise Level According to Standards?
24/04/y 15:36:34

In environmental noise reports or technical specifications of household appliances, we often encounter the figure 50dB. But in reality, does a 50dB noise level cause discomfort or affect health?

How to maintain the ideal soil electrical conductivity (EC) index
11/04/y 11:18:14

The EC index reflects the amount of dissolved salts present in the soil solution. When this level changes, the nutrient status and the root's absorption capacity also change. This is why EC is often monitored throughout the cultivation process.

Factors affecting the electrical conductivity (EC) in soil
11/04/y 09:31:50

According to specialized literature, the electrical conductivity (EC) of soil is typically between 0.2 and 1.2 mS/cm. This is the range within which plants can absorb nutrients relatively stably. When it falls below this threshold, the amount of dissolved ions is insufficient, leading to nutrient deficiencies. When it exceeds this threshold, the salt content increases, affecting plant growth.

Monitor the electrical conductivity of water sources using an EC meter
10/04/y 10:27:53

Electrical conductivity (EC) is a fundamental parameter in water quality assessment. This index reflects the ability of a solution to conduct electricity through dissolved ions, including metal salts and inorganic compounds such as NaCl, KCl, nitrates, or phosphates

Is it difficult to find groundwater around a habitat?
06/04/y 17:02:02

Groundwater is the amount of water that accumulates in the pores of the soil or in the cracks of bedrock beneath the surface. This water source is not a free-flowing river but usually exists in aquifers. However, groundwater does not always exist as large streams but is often hidden within complex geological structures.
