Soil Amendments Buying Guide For Hydroponics: Everything You Need To Know


Hydroponics is a gardening technique that utilizes mineral nutrient solutions to grow crops without the need for soil. Soil amendments are additives like compost, manure or synthetic nutrients used to improve soil structure and fertility. In this guide, we’ll provide an overview of the different types of soil amendments available for hydroponic gardens, their uses and benefits as well as advice on how to choose the right one for your system.


What is a Soil Amendment?

A soil amendment is any product added to the existing soil in order to increase its fertility or improve its texture and drainage characteristics. This can include composts, manures and synthetically manufactured fertilizers. These products help to increase the water-holding capacity of soils, improve aeration and drainage, provide essential plant nutrients as well as provide some protection from disease.


What are the Different Types of Soil Amendments?

There are many different types of soil amendments available, each with its own set of benefits that can be used to enhance hydroponic gardens. These include organic composts such as peat moss or bark mulch, manures such as sheep manure or horse manure, synthetic fertilizers containing elements like nitrogen and phosphorus, vermiculite and perlite for improved soil structure and aeration as well as gypsum for better water absorption.


What are the Benefits of Using Soil Amendments?

Soil amendments have a range of benefits when it comes to improving the fertility and texture of soils as well as providing essential plant nutrients. Composts provide a slow-release source of nitrogen, phosphorus and other minerals which can help to boost growth while manures can improve soil structure, drainage and water retention. Synthetic fertilizers are a good choice for those looking to increase their nutrient levels quickly while vermiculite and perlite are great for improving aeration and drainage. Gypsum is also effective at improving water absorption in clay soils.


How Do I Choose the Right Soil Amendment?

When choosing a soil amendment it’s important to consider your particular needs based on the type of plants you’re growing as well as your budget. If you have a large area to cover, it may be worth investing in a bulk option such as compost or manure. If you’re looking for a quick boost of nutrients, then synthetic fertilizers are the way to go.Vermiculite and perlite are great for improving soil structure while gypsum can help with clay soils.


What is the Best Way to Apply Soil Amendments?

The best way to apply soil amendments will depend on the product you’ve chosen and your particular needs. For example, organic composts should be mixed into existing garden beds or potting mix at a rate of one part compost to two parts existing soil. Manures should also be mixed in with existing soil but at a lower ratio of one part manure to four parts existing soil. Synthetic fertilizers can be applied directly to the surface of the garden bed or potting mix and should be watered in. Vermiculite and perlite should also be incorporated into existing soil while gypsum is best when applied at a rate of 10kg/m2 once a year.


Soil amendments are a great way to improve soil fertility, texture and drainage as well as provide essential nutrients for plants. There are many different types available including organic composts, manures, synthetic fertilizers, vermiculite, perlite and gypsum each with their own unique benefits. It’s important to choose the right product for your particular needs based on budget and what you’re hoping to achieve. Application methods will vary depending on the product but most should be mixed into existing soil or potting mix and watered in well.
