Not every nutrient gap looks the same. If your soil test is showing adequate nitrogen and phosphorus but your fruits are undersized, your Brix is low, or your root crops aren't bulking the way they should, potassium is likely the missing piece.
Micro 5000 Organic™ is a focused 0-0-15 foliar spray that lets you address potassium deficiency directly, without throwing off the rest of your nutrient balance. Derived from kelp and OMRI-listed for certified organic production, it's a clean, targeted tool for orchards, vineyards, vegetable operations, and serious home growers who know what their crops actually need.
1 package ~ 150 grams
Why Use Micro 5000 Organic™?
- Targeted Potassium Delivery: At 0-0-15, this is a pure potassium fertilizer, but combined with beneficial living microbes for increased intake.
- Critical for Fruit & Root Crops: Potassium drives fruit sizing, sugar development, and shelf life in crops like tomatoes, peppers, grapes, strawberries, and fruit trees. For root crops—potatoes, sweet potatoes, carrots, and beets—it's essential for bulking and storage quality. If you're growing either, these are some of your most potassium-hungry crops.
- Foliar Speed When Timing Matters: Potassium deficiency during fruit set or root bulking can cost you yield and quality fast. Foliar application delivers nutrients quickly, which is critical when you're in a narrow window and can't wait on soil applications to catch up.
-
Safe for Organic Production: OMRI-listed for certified organic production systems.
How to Use:
Can apply up to 150 grams (1 package) per acre, mixed with ~ 20 gallons of water. If you wish to split applications, you can do two applications of 75 grams, mixed with 10 gallons. Can be applied multiple times throughout the growing season, depending on your crops and soil fertility.
Tips for Best Use:
- Get a soil test first. Micro 5000 works best when you've confirmed a potassium deficiency or know your crop's K demand is outpacing your soil's supply.
- Spray in the early morning or evening when stomata are most open and temperatures are cooler for maximum absorption.
- Time applications around your crop's peak potassium demand: for fruiting crops, that's fruit set through ripening; for root crops, it's during active bulking.
- Avoid applying when rain is expected within a few hours, as this reduces how much the plant can absorb before it's washed off.
- Pair with Spectrum + Myco™ at planting to build strong root biology. A well-functioning root system makes your entire fertility program more efficient, foliar included.

Great quality for price after 3 years of use
Color: Matte Navy, Size: 6-Quart, Color: Matte Navy, Size: 6-Quart
I’m 3.5 years in and use it weekly. So far it’s been a great product especially for the price. We are really into soups, roast, and I bake bread a lot. This thing is amazing and a great quality. It’s easy to clean, does great in the oven, and stands up great to constant use. I only have a small amount of staining at the bottom, and a couple scratches from metal utensils. The lid is solid and the handle is really secure still, which is a problem I’ve had with other brands I’ve tried.

Quality product
Color: Navy, Size: 6-Quart
I absolutely LOVE my Dutch oven! The reduced cooking time for certain cuts of meat for stews, pot roast, etc., is a definite game changer!! The meat comes out so juicy and tender. I made curry and did the "burning" of the curry and was hesitant because I didn't want the pot to be stained. There were no stains left at all. I've used it numerous times since purchasing and it still looks new. It's very durable and the color is beautiful. If you're looking for a functional, quality, and durable Dutch oven without breaking the bank, this is it! I highly recommend.

Nothing Exceptional but Gets the Job Done
Color: Blue, Size: 4.3-Quart, Color: Blue, Size: 4.3-Quart
I’ve owned this 4.5 Qt. Amazon Enameled Cast Iron Dutch Oven for almost two months and have used it three times to date. Upon arrival and at first glance, the gradient blue color is beautiful and super glossy; most importantly, the pot is heavy for its size - as it should be. It looks exactly like the product pictures, with a globular shape than square shape as others. Unfortunately, I also noticed that there was one pin hole and two tiny uneven protrusions on the enamel inside the pot.
I own three other enameled cast iron cookware from two other brands (photos attached for size comparison) and performance wise, this cast iron by Amazon performs equally to them. The pot isn’t exceptional or special but it gets the job done. Other than the pin holes and protrusions, I have no complaints. This isn’t my first rodeo so when heating up the pot and while cooking, I have zero issues.
I am starting the pan off at 4-Stars and will update my review as time progresses, or if I have any major issues with its durability or performance in subsequent months. For the amateur home cook, or for anyone who is new to cast iron cooking, below I’ve included tips that you may find useful while using this or any other enameled cast iron cookware.
================================
Regarding the 3 Photos and 1 video I've Attached:

================================
TIPS THAT YOU MAY FIND USEFUL While Using your cast iron dutch oven:
(Note: I included these similar tips in my review of a different enameled cast iron pot from a different brand. My tips can apply to all enameled cast iron cookware)
1. If you find that you have issues with food sticking, it could be that you are not heating up your cast iron pot properly to prevent undue hot spots.
I heat my pot up gradually starting at low, then medium, then high heat. After my pot is very hot is when I add my fat/cooking oil. As the oil is heating up in the pot, I lift it and swirl the oil around to coat all sides of the pot that will come in contact with food.
2. Take into consideration the temperature of the items you are adding to your heated pot. As a general rule for cooking: when ever possible, ensure that the items you are adding to a hot pot are at room temperature, rather than ice cold from the fridge; this will assist with even cooking.
3. Also, get comfortable with adjusting your heat by lowering and raising it based on what you’ve added to the pot. In general, you will need more heat at the beginning of the cooking process, and less heat towards the end. If you cook by recipe, I highly recommend that you read all the steps ahead before starting, so that you become familiarized with all the procedures, allowing you to maneuver accordingly when you start cooking.
4. At the exception of searing meat to achieve a brown crust, deep frying, or when caramelizing onions, you should be stirring your pot (I recommend using a wooden spoon) every few minutes when cooking in cast iron that is placed over high heat. If you are braising on the stove at low heat versus braising in the oven, the frequency of your stirring will need to be adjusted. No matter how you’re cooking though, a watchful eye on the pot plus stirring, should both be a habit not an afterthought.
5. For all cooking vessels in general but especially for cast iron: after cooking, allow your pot to cool down completely before cleaning. NEVER immerse a hot cast iron pot into cold water, nor pour cold dish water into hot pot. You risk not only being scald by dangerous steam, but you also risk weakening the enamel, therefore lessening the durability of your pots over time.
6. This cookware and others like it from Tramontina and Lodge are economical and if used correctly, will perform well for most cooking; if used correctly, they should also last for years. Nonetheless, if you can afford it, authentic enameled cast iron cookware made in France by Le Creuset is the best way to go. Le Creuset is the gold standard in cast iron cookware and their quality is second to none. I definitely recommend this Amazon dutch oven but if you can afford to splurge, Le Creuset's reputation is stellar. As a professional chef, I've used them in high end kitchens and their quality and performance is premier.

Nice BIG enameled cast iron dutch oven. like LeCreuset but costs less
Color: Blue, Size: 6-Quart
This is nice quality, similar to the far more costly French LeCreuset brand. I was surprised how big this model is, possibly too big for my small kitchen and limited storage space. I store it in the oven. It would be great for baking sourdough boule bread.
