Soil bulk density meter

This entry is provided by TOP Cloud Farming Equipment Network

Soil bulk density should be called dry bulk density, also known as soil specific gravity. The ratio of the weight of a certain volume of soil (including soil grains and pores between grains) after drying to the water volume of the same volume. The mass or weight (g / cm ^ 3 or ton / meter ^ 3) of a unit volume of soil (including soil particles and pores) under the condition of natural barrier in the field is called soil bulk density. The soil density meter is suitable for measuring the density of coarse-grained soil on the spot. It has a chassis, a sand filling funnel, a density bottle, and a valve.

Introduction

    Soil bulk density should be called dry bulk density, also known as soil specific gravity. The ratio of the weight of a certain volume of soil (including soil grains and pores between grains) after drying to the weight of water of the same volume. The mass or weight (g / cm ^ 3 or ton / meter ^ 3) of a unit volume of soil (including soil particles and pores) under the condition of natural barrier in the field is called soil bulk density. The soil density meter is suitable for measuring the density of coarse-grained soil on the spot. It has a chassis, a sand filling funnel, a density bottle, and a valve.

principle

    Soil bulk density The soil bulk density is determined by the amount of soil pores and soil solids. From the soil bulk density, the weight of any unit of soil can be calculated. The formula is: soil weight = volume × bulk weight. For example, the cultivated area is 667 square meters, the thickness of the cultivation layer is 0.15m, the soil bulk density is 1.34g / cm3 (1340kg / m3, 1.34T / m3), and the soil weight is:
    667 × 0.15 × 1.34 × 1000 = 134067kg.

Function parameter

    Sand container: 4L;
    Instrument size: 300 x 300 x 445mm (L x W x H);
    Weight: 1.5Kg;
