Best Fertiliser For Sweet Corn

Sweet corn is a popular vegetable that can be grown in gardens all over the world. It is easy to grow and can be grown in containers if your garden does not have enough space for it. Sweet corn will produce large ears containing many kernels, which are sweet and tasty when cooked on the cob or eaten raw. You should plant sweet corn seeds in early spring so that they have time to grow and produce fruit before fall arrives.

Planting sweet corn seeds is easy as long as you follow some basic rules: firstly make sure that your soil has good drainage; secondly, make sure that it has plenty of organic matter; thirdly add some compost or manure into the soil before planting seeds; fourthly sow seeds at least 1 inch deep into prepared soil; fifthly water regularly until plants emerge above ground level (about two weeks).

Corn is a heavy feeder plant that needs continuous nutrition throughout its growing cycle. The best fertilizers for sweet corn are those that are high in nitrogen, phosphorus, and potassium. Nitrogen is the nutrient most needed by the corn plant, but you also need to make sure that the other major nutrients (phosphorus and potassium) are present in your soil. Corn grown on poor soils may not produce full ears of kernels and will have fewer rows than usual.

Cottonseed Meal

Cottonseed meal is a significant source of nitrogen, phosphorus, potassium, and protein. It also contains amino acids, micronutrients (like sulphur), and fibre.

The price of a cottonseed meal can vary depending on where you purchase it from; however, it tends to be more expensive than other fertilizers such as blood meals or bone meals.

Alfalfa Meal or Pellets

Alfalfa meal is a good source of nitrogen, phosphorus, and potassium. Alfalfa meal is also a good source of calcium and magnesium. Additionally, alfalfa meal provides sulfur which can be used as an alternative to commercial fertilizer for sweet corn.

Additionally, you can use alfalfa meal as a source of amino acids for your sweet corn plants if they need some additional nutrients in their diet.

Composted Manure

Composted manure is a great source of nitrogen and phosphorus. It can also be a good source of potassium, but in most cases, you will have to apply additional fertilizer to the soil to make up for any shortage in this macronutrient. Composted manure is also a good source of micronutrients like copper, manganese, and zinc.

The price of composted manure varies depending on where you live and which company you buy it from. If you buy in bulk then the price per tonne will typically be lower than if you were buying smaller quantities at a time.

Blood Meal

A blood meal is one of the best fertilizers for sweet corn. It has a slightly acidic pH, so it can be used on soil that is too alkaline. Blood meal also contains nitrogen, which will help to improve growth and yield in your sweet corn plants.

You can get blood meal at any garden centre or hardware store. It’s also available online on sites like Amazon or eBay if you prefer to buy it that way instead of going out in person.

A blood meal should be applied when planting your sweet corn seeds into the ground in late spring or early summer (depending on where you live). The best time of day for applying this fertilizer is just before dark because this allows time for the nutrients from it to reach their target before the sun comes up again tomorrow morning – making sure they’re immediately available when needed later on down the road. Apply no more than 10lbs per acre (4kg/hectare) with only 2-3lbs per 1000 square foot bed area.”

Earthworm Castings

Earthworm castings are an excellent organic soil amendment that can be used as a fertilizer. They come from the earthworm’s digestive system and contain a wide variety of nutrients and beneficial microorganisms for plants. Earthworm castings are high in potassium, phosphorus, micronutrients, and organic matter. If you’re looking for a natural way to fertilize your corn plants without adding any chemicals or synthetic fertilizers into their environment then earthworm castings are an excellent choice.

Earthworm castings have long been considered one of nature’s best fertilizers for growing plants because it contains many different types of nutrients including calcium (Ca), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), molybdenum (Mo) zinc (Zn). These minerals help promote healthy root systems which lead to higher yields per acreage over time

Fish Emulsion

Fish emulsion is a liquid fertilizer made from fish waste. It’s an organic fertilizer, so it has all the benefits of that type of fertilizer as well as some additional benefits:

  • it contains nitrogen and phosphorus
  • fish emulsion is a good source of nitrogen and phosphorus
  • it also contains trace minerals, vitamins, and other nutrients in small amounts (so don’t think this will solve all your nutrient deficiencies)
  • price: $10-$15 per gallon

How To Apply

Fertilizer can be applied to the soil before planting, or it can be added to the water when watering the sweet corn.

  • For a small area of 1-2m2, 2g (1/4oz) will cover that area with enough fertilizer for your plants to absorb.
  • For larger areas, you’ll need to increase the amount applied. The same principle applies – add 2g per square metre of the area and then work that into the soil at least 10 days before planting. If using liquid fertilizer, add this straight onto your sweet corn seedlings when they emerge and then water well after each application as above.
  • You should apply fertilizers regularly throughout spring, summer, and autumn, and especially between sowings in early spring.

When To Apply

Corn is a heavy feeder, so your crop will need lots of nitrogen, phosphorus, and potassium to grow and produce healthy ears. These three nutrients are called primary nutrients. Your soil’s pH level will also affect how much fertilizer you should apply—the higher the pH level, the more nutrients that need to be added.

To encourage maximum production from your sweet corn plants:

  • Apply fertilizer when you first plant in springtime (about three weeks before planting). This provides nitrogen for early growth.
  • Apply an additional application when about one-third of the plants have emerged from ground level (about 30 days after planting). This provides more nitrogen for early growth as well as phosphorus and potassium for later on in the life cycle

Corn is a really heavy feeder so it needs lots of nitrogen, phosphorus, and potassium to grow and produce healthy ears. No fertilizer can substitute a healthy soil structure, but you can use different types of fertilizers depending on the nutritional content of your soil.

If your soil test shows that there is plenty of phosphorous (P) but it’s lacking in nitrogen (N), you may want to apply a high-nitrogen fertilizer. If there isn’t enough available phosphorus in the soil for corn, consider applying some rock phosphate before planting or adding composted manure during the growing season.


It is also important to make sure that you don’t over-fertilize your corn plants because this can lead to slow growth or even death. You should get a soil test done before adding any fertilizer so you know what nutrients are needed for your sweet corn. The best way to apply fertilizer for sweet corn is by using a drop spreader which distributes it evenly around each plant without over-fertilizing them. This will ensure an even distribution of nutrients while avoiding any burning of the leaves and stems from direct contact with the fertilizer granules.
