Pure Live Seed (PLS) Calculator

Pure Live Seed (PLS) is a critical metric in agriculture. To calculate it, multiply the percent purity (as a decimal) by the percent germination (as a decimal) and divide by 100. PLS represents the viable, pure seeds in a batch, crucial for accurate seeding rate calculations and successful crop establishment. It ensures you’re sowing high-quality, capable seeds for optimal results.

Term	Definition
Pure Seed (PS)	The weight of all seeds in a sample, excluding all non-seed materials (expressed as a percentage).
Germination Rate (GR)	The percentage of seeds in the sample that are capable of germinating.
Purity (P)	The percentage of pure, viable seeds in a sample.
Pure Live Seed (PLS)	The portion of the sample that is both pure (free of contaminants) and capable of germinating.
Calculation	PLS = (PS * GR * P) / 100

FAQs

How do you calculate pure live seed? Pure Live Seed (PLS) is calculated by multiplying the percent purity (as a decimal) by the percent germination (as a decimal) and dividing by 100. The formula is: PLS = (Percent Purity * Percent Germination) / 100.

What is the PLS seeding rate? The PLS seeding rate is the rate at which you should sow seeds based on the PLS value. It varies depending on the type of crop or plant you are seeding. Typically, the recommended PLS seeding rate is provided on the seed packaging or by agricultural extension services.

What does the percent pure live seed tell us? The percent pure live seed tells you the proportion of seeds in a batch that are both pure (free of contaminants) and capable of germinating. It indicates the quality of the seed lot.

What is the pure live seed related to? Pure live seed is related to the quality and viability of seeds, which affects the success of germination and crop establishment.

How do I calculate how much seed I need? To calculate how much seed you need, you’ll need to consider factors like the type of crop, the planting method, the desired plant density, and the recommended seeding rate for that crop.
